Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for Term<'db>

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

Formats the value using the given formatter.

fn from(value: Const<'db>) -> Term<'db>

Converts to this type from the input type.

impl<'db> From<Term<'db>> for GenericArg<'db>

fn from(value: Term<'db>) -> GenericArg<'db>

Converts to this type from the input type.

impl<'db> From<Ty<'db>> for Term<'db>

fn from(value: Ty<'db>) -> Term<'db>

Converts to this type from the input type.

impl<'db> Hash for Term<'db>

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

where __H: Hasher,

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<'db> HirDisplay<'db> for Term<'db>

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

fn into_displayable<'a>( &'a self, db: &'db (dyn HirDatabase + 'static), 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 + 'static), 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 + 'static), 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 + 'static), 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 + 'static), module_id: ModuleIdLt<'static>, 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 + 'static), 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 + 'static), 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

fn eq(&self, other: &Term<'db>) -> 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.
