Struct User

pub struct User {
    pub name: String,
    pub external_metadata: Option<ExternalUserMetadata>,
    pub internal_metadata: Option<InternalUserMetadata>,
}

Identifies a user.

Fields

name: String

The name of the user within the system.

external_metadata: Option<ExternalUserMetadata>

Metadata about this user in an external system.

internal_metadata: Option<InternalUserMetadata>

Implementations

impl User

pub fn is_internal(&self) -> bool

Returns whether this is an internal user.

pub fn is_external_admin(&self) -> bool

Returns whether this user is an admin in an external system.

pub fn is_internal_admin(&self) -> bool

pub fn is_superuser(&self) -> bool

Returns whether this user is a superuser.

pub fn is_system_user(&self) -> bool

Returns whether this is user is the mz_system user.

pub fn limit_max_connections(&self) -> bool

Returns whether we should limit this user’s connections to max_connections

pub fn kind(&self) -> UserKind

Returns the kind of user this is.

Trait Implementations

impl Clone for User

fn clone(&self) -> User

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for User

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

Formats the value using the given formatter.

impl From<&User> for UserMetadata

fn from(user: &User) -> UserMetadata

Converts to this type from the input type.

impl PartialEq for User

fn eq(&self, other: &User) -> 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 Serialize for User

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Var for User

fn name(&self) -> &'static str

Returns the name of the configuration parameter.

fn value(&self) -> String

Constructs a flattened string representation of the current value of the configuration parameter.

fn description(&self) -> &'static str

Returns a short sentence describing the purpose of the configuration parameter.

fn type_name(&self) -> Cow<'static, str>

Returns the name of the type of this variable.

fn visible(&self, _: &User, _: &SystemVars) -> Result<(), VarError>

Indicates wither the Var is visible as a function of the user and system_vars. “Invisible” parameters return VarErrors.

fn is_unsafe(&self) -> bool

Reports whether the variable is only visible in unsafe mode.

fn as_var(&self) -> &dyn Var

where Self: Sized,

Upcast self to a dyn Var, useful when working with multiple different implementors of Var.
