pub struct PostageContext { /* private fields */ }

Context for postage validation.

Contains the current state needed to determine whether batches are expired or usable. This data may come from a blockchain, database, or any other source.

Implementations

impl PostageContext

pub const fn new(block: u64, total_amount: u128) -> Self

Creates a new postage context.

pub const fn block(&self) -> u64

Returns the current block number.

pub const fn total_amount(&self) -> u128

Returns the cumulative payout per chunk.

pub const fn set_block(&mut self, block: u64)

Updates the block number.

pub const fn set_total_amount(&mut self, total_amount: u128)

Updates the total amount.

Trait Implementations

impl Clone for PostageContext

fn clone(&self) -> PostageContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PostageContext

impl Debug for PostageContext

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

Formats the value using the given formatter.

impl Default for PostageContext

fn default() -> PostageContext

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PostageContext

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PostageContext

impl PartialEq for PostageContext

fn eq(&self, other: &PostageContext) -> 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.

impl Serialize for PostageContext

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
