Trait ErrorTolerantParser 

pub trait ErrorTolerantParser<'ast, T> {
    // Required methods
    fn parse_tolerant<'input>(
        &self,
        alloc: &'ast AstAlloc,
        file_id: FileId,
        lexer: impl Iterator<Item = Result<SpannedToken<'input>, LexicalError>>,
    ) -> Result<(T, ParseErrors), ParseError>;
    fn parse_strict<'input>(
        &self,
        alloc: &'ast AstAlloc,
        file_id: FileId,
        lexer: impl Iterator<Item = Result<SpannedToken<'input>, LexicalError>>,
    ) -> Result<T, ParseErrors>;
}

General interface of the various specialized Nickel parsers.

T is the product of the parser (a term, a type, etc.).

Required Methods

fn parse_tolerant<'input>( &self, alloc: &'ast AstAlloc, file_id: FileId, lexer: impl Iterator<Item = Result<SpannedToken<'input>, LexicalError>>, ) -> Result<(T, ParseErrors), ParseError>

Parse a value from a lexer with the given file_id in an error-tolerant way. This methods can still fail for non-recoverable errors.

fn parse_strict<'input>( &self, alloc: &'ast AstAlloc, file_id: FileId, lexer: impl Iterator<Item = Result<SpannedToken<'input>, LexicalError>>, ) -> Result<T, ParseErrors>

Parse a value from a lexer with the given file_id, failing at the first encountered error.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
