Struct PragmaMap 

#[non_exhaustive]
pub struct PragmaMap { /* private fields */ }

Explicit pragma transition timeline.

Implementations

impl PragmaMap

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

Return the immutable snapshot active at the given byte offset.

pub fn state_at(&self, offset: usize) -> PragmaState

Return the concrete pragma state active at the given byte offset.

pub fn final_state(&self) -> PragmaState

Return the final top-level pragma state after all lexical restores.

pub fn cursor(&self) -> PragmaQueryCursor

Create a cursor for monotonic queries against this map.

pub fn entries(&self) -> &[PragmaEntry]

Return all transition entries in source order.

pub fn to_tuples(&self) -> Vec<(Range<usize>, PragmaSnapshot)>

Convert this map to the legacy tuple representation.

Trait Implementations

impl Clone for PragmaMap

fn clone(&self) -> PragmaMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PragmaMap

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

Formats the value using the given formatter.

impl Default for PragmaMap

fn default() -> PragmaMap

Returns the “default value” for a type.

impl PartialEq for PragmaMap

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