Enum FragmentParseError 

pub enum FragmentParseError {
    Lex(LexError),
    Parse(TokenParseError),
    MultipleCells {
        count: usize,
    },
}

An error produced while lexing or parsing one typed syntax fragment.

Variants

Lex(LexError)

The source could not be converted into token trees.

Parse(TokenParseError)

The token trees did not match the requested fragment type.

MultipleCells

The source contained top-level cell boundaries and therefore was not a single fragment.

Fields

count: usize

The number of cells produced by the lexer.

Trait Implementations

impl Clone for FragmentParseError

fn clone(&self) -> FragmentParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FragmentParseError

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

Formats the value using the given formatter.

impl Display for FragmentParseError

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

Formats the value using the given formatter.

impl Eq for FragmentParseError

impl Error for FragmentParseError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<LexError> for FragmentParseError

fn from(error: LexError) -> Self

Converts to this type from the input type.

impl From<TokenParseError> for FragmentParseError

fn from(error: TokenParseError) -> Self

Converts to this type from the input type.

impl PartialEq for FragmentParseError

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

Equality operator ==.

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

Inequality operator !=.
