Enum MmapError

pub enum MmapError {
    FailedToMapMemory(i32),
    MappingFailed(String),
    FailedToGetFileSize,
}

Represents errors that can occur during memory mapping.

Variants

FailedToMapMemory(i32)

Failed to map memory on Unix.

MappingFailed(String)

Generic mapping failure with a message.

FailedToGetFileSize

Failed to get file size.

Implementations

impl MmapError

pub fn failed_to_map_memory_unix(error_code: i32) -> Self

pub fn mapping_failed(message: &str) -> Self

pub fn failed_to_get_file_size() -> Self

Trait Implementations

impl Debug for MmapError

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

Formats the value using the given formatter.

impl Display for MmapError

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

Formats the value using the given formatter.

impl Error for MmapError

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 PartialEq for MmapError

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

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

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

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