Enum ParsingResult 

pub enum ParsingResult<T> {
    Ok(T),
    Failed(Vec<Diagnostic>),
    Partial(T, Vec<Diagnostic>),
}

Result of parsing.

Variants

Ok(T)

Fully valid ast that was parsed without errors.

Failed(Vec<Diagnostic>)

The ast contain invalid starting tokens, and cannot be parsed.

Partial(T, Vec<Diagnostic>)

The ast can be partially parsed, but some tokens was skipped during parsing, or their meaning was changed.

Implementations

impl<T> ParsingResult<T>

pub fn from_parts(value: Option<T>, errors: Vec<Diagnostic>) -> Self

Create new ParsingResult from optional value and accumulated errors.

pub fn into_result(self) -> Result<T>

Convert into syn::Result, with fail on first diagnostic message, Ignores any diagnostic non error message when result is available. Returns Error on ParsingResult::Failed, and ParsingResult::Partial.

pub fn split(self) -> (Option<T>, Vec<Diagnostic>)

pub fn push_diagnostic(&mut self, diagnostic: Diagnostic)

pub fn is_ok(&self) -> bool

impl<T> ParsingResult<Vec<T>>

pub fn split_vec(self) -> (Vec<T>, Vec<Diagnostic>)

pub fn from_parts_vec(value: Vec<T>, errors: Vec<Diagnostic>) -> Self
