Struct ValidityError
pub struct ValidityError<Src, Dst: ?Sized + TryFromBytes> { /* private fields */ }The error emitted if the conversion source contains invalid data.
Implementations
impl<Src, Dst: ?Sized + TryFromBytes> ValidityError<Src, Dst>
fn into_src(self) -> SrcProduces the source underlying the failed conversion.
fn map_src<NewSrc>(self, f: impl FnOnce(Src) -> NewSrc) -> ValidityError<NewSrc, Dst>Maps the source value associated with the conversion error.
This can help mitigate [issues with
Send,Syncand'staticbounds][self#send-sync-and-static].Examples
use *; let source: u8 = 42; // Try to transmute the `source` to a `bool`. This will fail. let maybe_bool: = try_transmute!; // Drop the error's source. let maybe_bool: = maybe_bool.map_err;
