Struct AllowedProposers 

#[non_exhaustive]
pub struct AllowedProposers {
    pub epoch: Option<u64>,
    pub proposers: Vec<u32>,
}

The validators allowed to propose a transaction in consensus.

Proposal by any other validator is byzantine behavior and invalidates the whole block.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

epoch: Option<u64>

The epoch whose committee proposers indexes into.

Committee indices are only meaningful against one committee, so a set recorded for any other epoch is ignored and the transaction is treated as naming no proposers.

proposers: Vec<u32>

Committee indices of the allowed proposers, strictly increasing and non-empty.

An empty list names no validator and is rejected; omit allowed_proposers entirely to let any validator propose the transaction.

Implementations

impl AllowedProposers

pub const EPOCH_FIELD: &'static MessageField

pub const PROPOSERS_FIELD: &'static MessageField

impl AllowedProposers

pub fn path_builder() -> AllowedProposersFieldPathBuilder

impl AllowedProposers

pub const fn const_default() -> Self

pub fn epoch_opt_mut(&mut self) -> Option<&mut u64>

If epoch is set, returns Some with a mutable reference to the value; otherwise returns None.

pub fn epoch_mut(&mut self) -> &mut u64

Returns a mutable reference to epoch. If the field is unset, it is first initialized with the default value.

pub fn epoch_opt(&self) -> Option<u64>

If epoch is set, returns Some with the value; otherwise returns None.

pub fn set_epoch(&mut self, field: u64)

Sets epoch with the provided value.

pub fn with_epoch(self, field: u64) -> Self

Sets epoch with the provided value.

pub fn proposers(&self) -> &[u32]

Returns the value of proposers, or the default value if proposers is unset.

pub fn proposers_mut(&mut self) -> &mut Vec<u32>

Returns a mutable reference to proposers. If the field is unset, it is first initialized with the default value.

pub fn set_proposers(&mut self, field: Vec<u32>)

Sets proposers with the provided value.

pub fn with_proposers(self, field: Vec<u32>) -> Self

Sets proposers with the provided value.

impl AllowedProposers

pub fn epoch(&self) -> u64

Returns the value of epoch, or the default value if epoch is unset.
