Struct CompileTimePragmaEnvironment 

pub struct CompileTimePragmaEnvironment { /* private fields */ }

Explicit compile-time pragma environment that can answer file-position queries and expose immutable snapshots.

Implementations

impl CompileTimePragmaEnvironment

pub fn build(ast: &Node) -> Self

Build a queryable environment from an AST.

pub fn query_at(&self, offset: usize) -> PragmaStateQuery

Return a position query object with immutable state snapshot.

pub fn snapshot_at(&self, offset: usize) -> PragmaSnapshot

Return the immutable snapshot active at the given byte offset.

pub fn as_map(&self) -> &[(Range<usize>, PragmaSnapshot)]

Access the underlying range map for advanced consumers.

Trait Implementations

impl Clone for CompileTimePragmaEnvironment

fn clone(&self) -> CompileTimePragmaEnvironment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompileTimePragmaEnvironment

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

Formats the value using the given formatter.

impl Default for CompileTimePragmaEnvironment

fn default() -> CompileTimePragmaEnvironment

Returns the “default value” for a type.

impl PartialEq for CompileTimePragmaEnvironment

fn eq(&self, other: &CompileTimePragmaEnvironment) -> 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.
