Struct witx::ParseError

pub struct ParseError {
    pub message: String,
    pub location: Location,
}

Parser turns s-expressions into unvalidated syntax constructs. conventions: Type::starts_parsing(s-expr) -> bool is for look-ahead: we use this predicate to combine parsers for different Types where both alternatives are accepted. Type::parse(sexpr: &SExpr) -> Result<Self, ParseError> takes a single s-expression and parses it into a Self. for parsers that take a subset of a vector s-expression, the signature Type::parse(sexprs: &[SExpr], location: Location) -> Result<Self, ParseError> has an additional Location argument, which should point to the parent SExpr::Vec. This is used for error reporting in case the slice doesn't have the number of elements expected.

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Fail for ParseError

fn name(&self) -> Option<&str>

Returns the "name" of the error.

fn cause(&self) -> Option<&dyn Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where
    D: Display + Send + Sync + 'static, 

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.
