Enum relay_dynamic_config::ErrorBoundary

pub enum ErrorBoundary<T> {
    Err(Arc<dyn Error + Send + Sync + 'static>),
    Ok(T),
}

Wraps a serialization / deserialization result to prevent error from bubbling up.

This is useful for keeping errors in an experimental part of a schema contained.

Variants

Err(Arc<dyn Error + Send + Sync + 'static>)

Contains the error value.

Ok(T)

Contains the success value.

Implementations

impl<T> ErrorBoundary<T>

pub fn is_ok(&self) -> bool

Returns true if the result is Ok.

pub fn is_err(&self) -> bool

Returns true if the result is Err.

pub fn ok(self) -> Option<T>

Converts from Result<T, E> to Option<T>.

pub fn unwrap_or_else<F>(self, op: F) -> T

where F: FnOnce(&(dyn Error + 'static)) -> T,

Returns the contained Ok value or computes it from a closure.

pub fn get_or_insert_with<F>(&mut self, f: F) -> &mut T

where F: FnOnce() -> T,

Inserts a value computed from f into the error boundary if it is Err, then returns a mutable reference to the contained value.

Trait Implementations
