Enum FromError

pub enum FromError {
    MissingNode,
    ParseIntError(ParseIntError),
    ParseFloatError(ParseFloatError),
}

Errors that can occur when converting an apollo-parser CST to an apollo-encoder one. These errors don’t give a lot of context at the moment. Before converting CSTs, you should make sure that your parse tree is complete and valid.

Variants

MissingNode

the parse tree is missing a node

ParseIntError(ParseIntError)

expected to parse a i32

ParseFloatError(ParseFloatError)

expected to parse a f64

Trait Implementations

impl Clone for FromError

fn clone(&self) -> FromError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FromError

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

Formats the value using the given formatter.

impl Display for FromError

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

Formats the value using the given formatter.

impl Error for FromError

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<ParseFloatError> for FromError

fn from(source: ParseFloatError) -> Self

Converts to this type from the input type.

impl From<ParseIntError> for FromError

fn from(source: ParseIntError) -> Self
