Enum StrContext 

#[non_exhaustive]
pub enum StrContext {
    Label(&'static str),
    Expected(StrContextValue),
}

Additional parse context for [ContextError] added via Parser::context

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Label(&'static str)

Description of what is currently being parsed

Expected(StrContextValue)

Grammar item that was expected

Trait Implementations

impl<'i> AddContext<LocatingSlice<&'i str>, StrContext> for ParseStack<'i>

fn add_context( self, _input: &Input<'i>, _token_start: &<Input<'i> as Stream>::Checkpoint, context: StrContext, ) -> Self

Add a new context entry to the current layer.

This provides backwards compatibility with winnow’s Parser::context API. The StrContext is internally converted to our owned StringContext representation.

Entries are staged inside Self until the current layer is closed.

impl Clone for StrContext

fn clone(&self) -> StrContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StrContext

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

Formats the value using the given formatter.

impl Display for StrContext

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

Formats the value using the given formatter.

impl Eq for StrContext

impl From<StrContext> for StringContext

fn from(context: StrContext) -> Self

Converts to this type from the input type.

impl PartialEq for StrContext

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

Equality operator ==.

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

Inequality operator !=.
