Struct serde_derive_internals::Ctxt

source · [−]

pub struct Ctxt { /* private fields */ }

Expand description

A type to collect errors together and format them.

Dropping this object will cause a panic. It must be consumed using check.

References can be shared since this type uses run-time exclusive mut checking.

Implementations

source

impl Ctxt

source

pub fn new() -> Self

Create a new context object.

This object contains no errors, but will still trigger a panic if it is not checked.

source

pub fn error_spanned_by<A: ToTokens, T: Display>(&self, obj: A, msg: T)

Add an error to the context object with a tokenenizable object.

The object is used for spanning in error messages.

source

pub fn syn_error(&self, err: Error)

Add one of Syn’s parse errors.

source

pub fn check(self) -> Result<(), Vec<Error>>

Consume this object, producing a formatted error string if there are errors.
