Struct RetryOrdinal 

pub struct RetryOrdinal(/* private fields */);

The zero-based invocation ordinal for one retry key.

RetryOrdinal::INITIAL identifies the first component call, which is not a retry. Ordinal r identifies the r-th re-invocation.

Implementations

impl RetryOrdinal

pub const INITIAL: Self

The ordinal of the initial, non-retried component call.

pub fn new(value: u32) -> Result<Self, FaultPolicyError>

Validates and constructs a retry ordinal.

Errors

Returns FaultPolicyError::RetryOrdinalOutOfRange above 65,535.

pub const fn get(self) -> u32

Returns the ordinal value.

pub const fn is_initial(self) -> bool

Returns whether this is the initial, non-retried call.

pub fn checked_next(self) -> Result<Self, FaultPolicyError>

Returns the next ordinal.

Errors

Returns FaultPolicyError::RetryOrdinalOutOfRange instead of wrapping past the bounded representation.
