Struct DebugSymbol

pub struct DebugSymbol { /* private fields */ }

When provided along with the source text, identifies a span of source code. Because they are passed around everywhere, the debug symbols used by Sphinx are very light weight. Just an index into the source text and a length. In order to be useful they must first be resolved using a DebugSymbolResolver.

Implementations

impl DebugSymbol

pub fn new(start: TokenIndex, length: TokenLength) -> Self

pub fn start(&self) -> TokenIndex

pub fn end(&self) -> TokenIndex

pub fn len(&self) -> TokenLength

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for DebugSymbol

fn clone(&self) -> DebugSymbol

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DebugSymbol

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

Formats the value using the given formatter.

impl Hash for DebugSymbol

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 PartialEq for DebugSymbol

fn eq(&self, other: &DebugSymbol) -> 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 TryFrom<(u32, u32)> for DebugSymbol

type Error = (u32, u32)

The type returned in the event of a conversion error.

fn try_from(tuple: (TokenIndex, TokenIndex)) -> Result<Self, Self::Error>

Performs the conversion.
