Describes why a C-style numeric format was rejected.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

FormatTooLong

The complete UTF-8 format exceeds the bounded native parsing contract.

Fields

byte_offset: usize

length: usize

maximum: usize

InteriorNul

The string contains a NUL byte and cannot be passed as one C string.

Fields

byte_offset: usize

UnterminatedDirective

A % directive is incomplete.

Fields

byte_offset: usize

MultipleConversions

More than one directive would consume a value argument.

Fields

byte_offset: usize

DynamicArgument

* requests another variadic width or precision argument.

Fields

byte_offset: usize

PositionalArgument

A positional argument such as %1$d was requested.

Fields

byte_offset: usize

UnsupportedFlag

The directive uses a non-portable or unsupported flag.

Fields

byte_offset: usize

flag: char

IncompatibleFlag

The flag is defined for printf but not for this numeric conversion.

Fields

byte_offset: usize

flag: char

conversion: char

WidthTooLarge

The requested field width exceeds the bounded native parsing contract.

Fields

byte_offset: usize

width: u32

maximum: u32

PrecisionTooLarge

The requested precision exceeds the bounded native parsing contract.

Fields

byte_offset: usize

precision: u32

maximum: u32

UnsupportedLength

The directive uses a length modifier that does not match the C carrier type.

Fields

byte_offset: usize

UnsupportedConversion

The directive is not a supported numeric conversion.

Fields

byte_offset: usize

conversion: char

TypeMismatch

The conversion is numeric but does not match the signedness or category of T.

Fields

byte_offset: usize

DirectiveTooLong

Dear ImGui copies directives into a fixed 32-byte stack buffer.

Fields

byte_offset: usize

length: usize

Implementations

impl NumericFormatError

pub fn byte_offset(&self) -> usize

Returns the byte offset where validation failed.

Trait Implementations

impl Clone for NumericFormatError

fn clone(&self) -> NumericFormatError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumericFormatError

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

impl Eq for NumericFormatError

impl Error for NumericFormatError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
