Struct Diagnostics 

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

Available on crate feature alloc only.

Collection of Diagnostics produced by a parse.

Returned by parse in Err when any diagnostic was emitted.

Implementations

impl Diagnostics

pub const fn new() -> Self

Creates an empty collection.

pub fn is_empty(&self) -> bool

Returns true if no diagnostics were collected.

pub fn into_inner(self) -> Vec<Diagnostic>

Consumes self and returns the inner vector of diagnostics.

pub fn iter(&self) -> impl Iterator<Item = &Diagnostic>

Iterates over the collected diagnostics.

Trait Implementations

impl Clone for Diagnostics

fn clone(&self) -> Diagnostics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Diagnostics

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

Formats the value using the given formatter.

impl Default for Diagnostics

fn default() -> Self

Returns the “default value” for a type.

impl Diagnostics for Diagnostics

fn emit_unknown_content(&mut self, text: &str, span: Span)

Called when the parser sees text it cannot interpret (e.g. invalid tokens).

fn emit_unexpected(&mut self, actual: &str, expected: &[TokenType], span: Span)

Called when the parser expected one of expected token types but found actual.

fn emit_parse_number_error( &mut self, value: &str, error: ParseNumberError, span: Span, )

Called when parsing a G/M/T number fails (e.g. overflow, invalid format).

fn emit_parse_int_error( &mut self, value: &str, _error: ParseIntError, span: Span, )

Called when parsing an N or O number fails (e.g. invalid integer, overflow).

impl PartialEq for Diagnostics

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