Struct ObjectId 

pub struct ObjectId {
    database: Option<Ident>,
    schema: Ident,
    object: Ident,
}

A canonical object identifier.

User objects are fully qualified (database.schema.object). System-schema objects (e.g. mz_catalog.mz_objects) carry database = None because system catalogs are outside any database.

Fields

database: Option<Ident>

schema: Ident

object: Ident

Implementations

impl ObjectId

pub fn new(database: String, schema: String, object: String) -> Self

Create a user-object ObjectId with the given database, schema, and object names.

The arguments are raw (unquoted) identifier values — e.g. file stems or catalog names. They are stored as Idents, which compare on the raw value and only quote when rendered (see the std::fmt::Display impl).

pub fn new_system(schema: String, object: String) -> Self

Create a system-schema ObjectId (no database). The caller is responsible for ensuring schema is a system schema.

pub fn database(&self) -> Option<&str>

Get the database name, or None for system-schema objects.

pub fn expect_database(&self) -> &str

Get the database name, panicking if this is a system-schema oid.

Use only in code paths that exclusively handle user objects (apply, promote, stage, etc.). System-schema oids never reach those paths because they are not project objects.

pub fn schema(&self) -> &str

Get the schema name.

pub fn object(&self) -> &str

Get the object name.

pub fn from_item_name( name: &UnresolvedItemName, default_database: &str, default_schema: &str, ) -> Self

Resolve an UnresolvedItemName into an ObjectId.

Name parts are resolved based on how many components are present:

• 1-part (object) — uses both default_database and default_schema.
• 2-part (schema.object) — database = None if schema is a system schema; otherwise default_database.
• 3-part (database.schema.object) — used as-is.

pub fn from_raw_item_name( name: &RawItemName, default_database: &str, default_schema: &str, ) -> Self

Resolve a RawItemName into a fully qualified ObjectId.

Unwraps the inner UnresolvedItemName and delegates to from_item_name.

pub fn to_unresolved_item_name(&self) -> UnresolvedItemName

Convert to an UnresolvedItemName (the reverse of from_item_name).

Produces a 3-part name for user objects and a 2-part name for system-schema objects (database = None).

pub fn default_db_schema_from_uri( file_uri: &Url, root: &Path, ) -> Option<(String, String)>

Parse an ObjectId from a fully qualified name string.

Arguments

• fqn - Fully qualified name in the format “database.schema.object”

Returns

ObjectId if the FQN is valid (has exactly 3 dot-separated parts)

Errors

Returns error if the FQN format is invalid Derive the default database and schema from a file’s URI.

Expects the file to be under <root>/models/<database>/<schema>/. Returns None if the path doesn’t match the expected layout.

Trait Implementations

impl Clone for ObjectId

fn clone(&self) -> ObjectId

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ObjectId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ObjectId

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ObjectId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<ObjectId> for FullyQualifiedName

fn from(id: ObjectId) -> Self

Converts to this type from the input type.

impl FromStr for ObjectId

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ObjectId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ObjectId

fn cmp(&self, other: &ObjectId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ObjectId

fn eq(&self, other: &ObjectId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ObjectId

fn partial_cmp(&self, other: &ObjectId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ObjectId

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
