Struct garando_pos::hygiene::SyntaxContext

pub struct SyntaxContext(_);

A SyntaxContext represents a chain of macro expansions (represented by marks).

Implementations

impl SyntaxContext

pub fn empty() -> Self

pub fn apply_mark(self, mark: Mark) -> SyntaxContext

Extend a syntax context with a given mark

pub fn remove_mark(&mut self) -> Mark

pub fn adjust(&mut self, expansion: Mark) -> Option<Mark>

Adjust this context for resolution in a scope created by the given expansion. This returns the expansion whose definition scope we use to privacy check the resolution, or None if we privacy check as usual (i.e. not w.r.t. a macro definition scope).

pub fn glob_adjust(
    &mut self,
    expansion: Mark,
    glob_ctxt: SyntaxContext
) -> Option<Option<Mark>>

Adjust this context for resolution in a scope created by the given expansion via a glob import with the given SyntaxContext. This returns None if the context cannot be glob-adjusted. Otherwise, it returns the scope to use when privacy checking (see adjust for details).

pub fn reverse_glob_adjust(
    &mut self,
    expansion: Mark,
    glob_ctxt: SyntaxContext
) -> Option<Option<Mark>>

Undo glob_adjust if possible:

pub fn modern(self) -> SyntaxContext

pub fn outer(self) -> Mark

Trait Implementations

impl Clone for SyntaxContext

impl Copy for SyntaxContext

impl Debug for SyntaxContext

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

Formats the value using the given formatter.

impl Default for SyntaxContext

fn default() -> SyntaxContext

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for SyntaxContext

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where

impl Eq for SyntaxContext

impl Hash for SyntaxContext

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,

impl Ord for SyntaxContext

fn cmp(&self, other: &SyntaxContext) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<SyntaxContext> for SyntaxContext

fn eq(&self, other: &SyntaxContext) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &SyntaxContext) -> bool

This method tests for !=.

impl PartialOrd<SyntaxContext> for SyntaxContext

fn partial_cmp(&self, other: &SyntaxContext) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &SyntaxContext) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &SyntaxContext) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &SyntaxContext) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &SyntaxContext) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SyntaxContext

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where
    S: Serializer,
