Struct DummyHumanizer

pub struct DummyHumanizer;

A bare-minimum implementation of ExprHumanizer.

The DummyHumanizer does a poor job of humanizing expressions. It is intended for use in contexts where polish is not required, like in tests or while debugging.

Trait Implementations

impl Debug for DummyHumanizer

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

Formats the value using the given formatter.

impl ExprHumanizer for DummyHumanizer

fn humanize_id(&self, _: GlobalId) -> Option<String>

Attempts to return a human-readable string for the relation identified by id.

fn humanize_id_unqualified(&self, _id: GlobalId) -> Option<String>

Same as above, but without qualifications, e.g., only foo for materialize.public.foo.

fn humanize_id_parts(&self, _id: GlobalId) -> Option<Vec<String>>

Like Self::humanize_id, but returns the constituent parts of the name as individual elements.

fn humanize_scalar_type(&self, ty: &ScalarType) -> String

Returns a human-readable name for the specified scalar type.

fn column_names_for_id(&self, _id: GlobalId) -> Option<Vec<String>>

Returns a vector of column names for the relation identified by id.

fn humanize_column(&self, _id: GlobalId, _column: usize) -> Option<String>

Returns the #column name for the relation identified by id.

fn id_exists(&self, _id: GlobalId) -> bool

Returns whether the specified id exists.

fn humanize_column_type(&self, typ: &ColumnType) -> String

Returns a human-readable name for the specified column type.
