Enum PreallocationLimitOverride 

pub enum PreallocationLimitOverride {
    UseConfig,
    NoLimit,
    Override(usize),
}

SeqLen level override of configured preallocation size limit.

Variants

UseConfig

Use the configuration’s preallocation size limit.

NoLimit

Override with no limit.

Override(usize)

Override with a specific limit, in bytes.

Implementations

impl PreallocationLimitOverride

pub const fn to_opt_limit_with_config<C: ConfigCore>(self) -> Option<usize>

Convert the given PreallocationLimitOverride to an Option<usize>, reconciling with the given configuration.

If the override is PreallocationLimitOverride::UseConfig, then the configuration’s preallocation size limit is returned. If the override is PreallocationLimitOverride::NoLimit, then None is returned. Otherwise, the override is returned.

pub const fn from_usize(limit: usize) -> Self

Convert a raw preallocation usize value to a PreallocationLimitOverride.

Handles special case values PREALLOCATION_SIZE_LIMIT_USE_CONFIG and PREALLOCATION_SIZE_LIMIT_DISABLED.
