Enum TryFromOutcome 

pub enum TryFromOutcome {
    Converted,
    Unsupported,
    Failed(Cow<'static, str>),
}

Outcome of a try_from vtable operation.

This enum encodes both the result and whether the source value was consumed, which is critical for correct memory management.

Variants

Converted

Conversion succeeded. The source value was consumed.

Unsupported

The source type is not supported by this converter. The source value was NOT consumed - caller retains ownership.

Failed(Cow<'static, str>)

Conversion failed after consuming the source. The source value WAS consumed - caller must not drop it.

Trait Implementations

impl Clone for TryFromOutcome

fn clone(&self) -> TryFromOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TryFromOutcome

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

Formats the value using the given formatter.

impl PartialEq for TryFromOutcome

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
