Struct ConvertBytesError

pub struct ConvertBytesError { /* private fields */ }

Error returned when a platform string cannot be converted to bytes or bytes cannot be converted to a platform string.

On unix-like platforms, this error is never returned. On Windows platforms, platform strings can only be converted to byte vectors (and conversely byte vectors to platform strings) when they contain valid UTF-8 contents.

This error is returned by bytes_to_os_str, os_string_to_bytes and os_str_to_bytes. See their documentation for more details.

Implementations

impl ConvertBytesError

pub const fn new() -> Self

Constructs a new, default ConvertBytesError.

Examples

const ERR: ConvertBytesError = ConvertBytesError::new();
assert_eq!(
    ERR.message(),
    "Could not convert between bytes and platform string"
);

pub const fn message(self) -> &'static str

Retrieve the exception message associated with this convert bytes error.

Examples

let err = ConvertBytesError::new();
assert_eq!(
    err.message(),
    "Could not convert between bytes and platform string"
);

Trait Implementations

impl Clone for ConvertBytesError

fn clone(&self) -> ConvertBytesError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConvertBytesError

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

Formats the value using the given formatter.

impl Default for ConvertBytesError

fn default() -> ConvertBytesError

Returns the “default value” for a type.

impl Display for ConvertBytesError

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

Formats the value using the given formatter.

impl Error for ConvertBytesError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl Hash for ConvertBytesError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ConvertBytesError

fn cmp(&self, other: &ConvertBytesError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ConvertBytesError

fn eq(&self, other: &ConvertBytesError) -> 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.

impl PartialOrd for ConvertBytesError

fn partial_cmp(&self, other: &ConvertBytesError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
