Why a memory.pools config could not be turned into a pool layout.

Variants

EmptyPoolList

memory.pools was an empty list.

ZeroSize

A size field that must be non-zero was zero.

Fields

field: &'static str

The offending field.

SliceLargerThanPage

max_slice_size exceeds page_size (a slice can never span pages).

Fields

page_size: u64

The page size in bytes (after alignment).

max_slice_size: u64

The maximum slice size in bytes (after alignment).

CapSmallerThanPage

max_pool_size is smaller than page_size (the cap can’t fit one page).

Fields

page_size: u64

The page size in bytes (after alignment).

max_pool_size: u64

The pool capacity in bytes.

TooManyPages

max_pool_size spans more pages of page_size than a pool can hold.

Fields

pages: u64

The number of pages the configuration asks for.

TooManyPools

The pool list has more entries than the pool routing can address.

Fields

count: usize

The number of entries in the configuration.

PresetUnavailable

The preset is not available in this build.

Fields

preset: &'static str

The preset name.

SlicedPoolsUnavailable

Sliced pools are not available in this build (exclusive_memory_only).

Trait Implementations

impl Clone for PoolConfigError

fn clone(&self) -> PoolConfigError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PoolConfigError

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

Formats the value using the given formatter.

impl Display for PoolConfigError

impl Eq for PoolConfigError

impl Error for PoolConfigError

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 PoolConfigError

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

Equality operator ==.

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

Inequality operator !=.
