Types
enumFloatErrorKind
enum FloatErrorKindClassifies why float parsing failed.
Rust’s equivalent enum is private; exposed here so callers can branch on it.
Variants
EmptyInvalidenumIntErrorKind
enum IntErrorKindClassifies why integer parsing or a narrowing integer conversion failed.
Same variants as Rust’s core::num::IntErrorKind.
Variants
EmptyInvalidDigitNegOverflowPosOverflowZerostructParseFloatError
struct ParseFloatErrorRepresents a failed float parse; returned by f32::from_str / f64::from_str.
Implements: Error
Fields
kind: FloatErrorKindClassifies the failure.
Methods
fn new(kind: FloatErrorKind) -> ParseFloatErrorCreates a ParseFloatError with the given kind.
fn source(self: &ParseFloatError) -> OptionstructParseIntError
struct ParseIntErrorRepresents a failed integer parse; returned by i32::from_str_radix / from_ascii / etc.
Implements: Error
Fields
kind: IntErrorKindClassifies the failure.
Methods
fn new(kind: IntErrorKind) -> ParseIntErrorCreates a ParseIntError with the given kind.
fn source(self: &ParseIntError) -> OptionstructTryFromIntError
struct TryFromIntErrorRepresents a failed try_from integer conversion: the value did not fit the target type.
Unlike Rust’s opaque core::num::TryFromIntError, the kind is public.
Implements: Error
Fields
kind: IntErrorKindClassifies the failure.
Methods
fn new(kind: IntErrorKind) -> TryFromIntErrorCreates a TryFromIntError with the given kind.
