Enum std::collections::TryReserveErrorKind

pub enum TryReserveErrorKind {
    CapacityOverflow,
    AllocError {
        layout: Layout,
        /* private fields */
    },
}
🔬This is a nightly-only experimental API. (try_reserve_kind #48043)

Details of the allocation that caused a TryReserveError

Variants

CapacityOverflow
🔬This is a nightly-only experimental API. (try_reserve_kind #48043)

Error due to the computed capacity exceeding the collection’s maximum (usually isize::MAX bytes).

AllocError

Fields

layout: Layout
🔬This is a nightly-only experimental API. (try_reserve_kind #48043)

The layout of allocation request that failed

🔬This is a nightly-only experimental API. (try_reserve_kind #48043)

The memory allocator returned an error

Trait Implementations

source 
impl From<LayoutError> for TryReserveErrorKind
source 
fn from(_: LayoutError) -> TryReserveErrorKind

Always evaluates to TryReserveErrorKind::CapacityOverflow.

source 
impl From<TryReserveErrorKind> for TryReserveError
source 
fn from(kind: TryReserveErrorKind) -> TryReserveError
Converts to this type from the input type.
source 
impl PartialEq for TryReserveErrorKind
source 
fn eq(&self, other: &TryReserveErrorKind) -> bool
This method tests for self and other values to be equal, and is used by ==.
1.0.0source 
fn ne(&self, other: &Rhs) -> bool
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
