Struct SyntaxContextId

pub struct SyntaxContextId(/* private fields */);

Interned SyntaxContextData.

Implementations

impl SyntaxContextId

pub const ROOT: Self = _

The root context, which is the parent of all other contexts. All [FileId]s have this context.

pub fn is_root(self) -> bool

pub fn into_u32(self) -> u32

Deconstruct a SyntaxContextId into a raw u32. This should only be used for deserialization purposes for the proc-macro server.

pub fn from_u32(u32: u32) -> Self

Constructs a SyntaxContextId from a raw u32. This should only be used for serialization purposes for the proc-macro server.

Trait Implementations

impl Clone for SyntaxContextId

fn clone(&self) -> SyntaxContextId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SyntaxContextId

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

Formats the value using the given formatter.

impl Display for SyntaxContextId

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

Formats the value using the given formatter.

impl Hash for SyntaxContextId

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 InternKey for SyntaxContextId

fn from_intern_id(v: InternId) -> Self

Create an instance of the intern-key from a u32 value.

fn as_intern_id(&self) -> InternId

Extract the u32 with which the intern-key was created.

impl Ord for SyntaxContextId

fn cmp(&self, other: &SyntaxContextId) -> 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 SyntaxContextId

fn eq(&self, other: &SyntaxContextId) -> 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 SyntaxContextId

fn partial_cmp(&self, other: &SyntaxContextId) -> 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.
