Required Methods

fn hir_fmt(&self, f: &mut HirFormatter<'_, 'db>) -> Result

Provided Methods

fn into_displayable<'a>( &'a self, db: &'db dyn HirDatabase, max_size: Option<usize>, limited_size: Option<usize>, omit_verbose_types: bool, display_target: DisplayTarget, display_kind: DisplayKind, closure_style: ClosureStyle, show_container_bounds: bool, ) -> HirDisplayWrapper<'a, 'db, Self>

where Self: Sized,

Returns a Displayable type that is human-readable.

fn display<'a>( &'a self, db: &'db dyn HirDatabase, display_target: DisplayTarget, ) -> HirDisplayWrapper<'a, 'db, Self>

where Self: Sized,

Returns a Displayable type that is human-readable. Use this for showing types to the user (e.g. diagnostics)

fn display_truncated<'a>( &'a self, db: &'db dyn HirDatabase, max_size: Option<usize>, display_target: DisplayTarget, ) -> HirDisplayWrapper<'a, 'db, Self>

where Self: Sized,

Returns a Displayable type that is human-readable and tries to be succinct. Use this for showing types to the user where space is constrained (e.g. doc popups)

fn display_limited<'a>( &'a self, db: &'db dyn HirDatabase, limited_size: Option<usize>, display_target: DisplayTarget, ) -> HirDisplayWrapper<'a, 'db, Self>

where Self: Sized,

Returns a Displayable type that is human-readable and tries to limit the number of items inside. Use this for showing definitions which may contain too many items, like trait, struct, enum

fn display_source_code<'a>( &'a self, db: &'db dyn HirDatabase, module_id: ModuleId, allow_opaque: bool, ) -> Result<String, DisplaySourceCodeError>

Returns a String representation of self that can be inserted into the given module. Use this when generating code (e.g. assists)

fn display_test<'a>( &'a self, db: &'db dyn HirDatabase, display_target: DisplayTarget, ) -> HirDisplayWrapper<'a, 'db, Self>

where Self: Sized,

Returns a String representation of self for test purposes

fn display_with_container_bounds<'a>( &'a self, db: &'db dyn HirDatabase, show_container_bounds: bool, display_target: DisplayTarget, ) -> HirDisplayWrapper<'a, 'db, Self>

where Self: Sized,

Returns a String representation of self that shows the constraint from the container for functions
