Enum full_moon::ast::AstError

pub enum AstError<'a> {
    Empty,
    NoEof,
    UnexpectedToken {
        token: Token<'a>,
        additional: Option<Cow<'a, str>>,
    },
}

An error that occurs when creating the ast after tokenizing

Variants

Empty

There were no tokens passed, which shouldn't happen normally

NoEof

Tokens passed had no end of file token, which shouldn't happen normally

UnexpectedToken

An unexpected token, the most likely scenario when getting an AstError

Fields of UnexpectedToken

token: Token<'a>

The token that caused the error

additional: Option<Cow<'a, str>>

Any additional information that could be provided for debugging

Trait Implementations

impl<'_> Owned for AstError<'_>

type Owned = AstError<'static>

What an owned version of the object looks like. Usually contains a 'static lifetime.

fn owned(&self) -> Self::Owned

Returns an owned version of the object.

impl<'a> Clone for AstError<'a>

fn clone(&self) -> AstError<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> PartialEq<AstError<'a>> for AstError<'a>

fn eq(&self, other: &AstError<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &AstError<'a>) -> bool

This method tests for !=.

impl<'a> Display for AstError<'a>

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

Formats the value using the given formatter.

impl<'a> Debug for AstError<'a>

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

Formats the value using the given formatter.

impl<'a> StructuralPartialEq for AstError<'a>

impl<'a> Error for AstError<'a>

fn description(&self) -> &str

This method is soft-deprecated.

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

The lower-level cause of this error, if any.

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

The lower-level source of this error, if any.

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

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

Returns a stack backtrace, if available, of where this error ocurred.

impl<'a> Serialize for AstError<'a>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl<'de: 'a, 'a> Deserialize<'de> for AstError<'a>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.
