Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Zero

Zero where zero is meaningless.

TooLarge

Above the maximum.

Fields

max: u64

The maximum.

TooSmall

Below the minimum.

Fields

min: u64

The minimum.

AboveGlobal

A per-listener or per-source cap above the global cap.

BelowTick

A deadline shorter than one timer tick.

WindowBelowCheck

The minimum-rate window is shorter than its check interval.

BudgetBelowWorkers

The buffer budget is below workers times the largest class times two.

Fields

need: u64

The smallest valid budget in bytes.

DescriptorLimit

The caps exceed the process’s descriptor limit.

Fields

have: u64

The descriptor limit.

need: u64

Descriptors the configuration needs.

Missing

A required part is not set.

NotListening

An adopted socket is not a listening socket.

Inconsistent

Values that contradict each other.

Malformed

A byte or character the value cannot contain (a NUL in a socket path).
