Enum EpochSpecifier

pub enum EpochSpecifier {
    Number(Epoch),
    Latest,
    LatestMinusOffset(u64),
}

Represents the different ways to specify an epoch when querying the API.

Variants

Number(Epoch)

Epoch was explicitly provided as a number (e.g., “123”)

Latest

Epoch was provided as “latest” (e.g., “latest”)

LatestMinusOffset(u64)

Epoch was provided as “latest-{offset}” (e.g., “latest-100”)

Implementations

impl EpochSpecifier

pub fn parse(epoch_str: &str) -> StdResult<Self>

Parses the given epoch string into an EpochSpecifier.

Accepted values are:

• a u64 number
• latest
• latest-{offset} where {offset} is a u64 number

Trait Implementations

impl Clone for EpochSpecifier

fn clone(&self) -> EpochSpecifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpochSpecifier

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

Formats the value using the given formatter.

impl Display for EpochSpecifier

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

Formats the value using the given formatter.

impl FromStr for EpochSpecifier

type Err = Error

The associated error which can be returned from parsing.

fn from_str(epoch_str: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for EpochSpecifier

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
