Struct Fee 

pub struct Fee {
    pub num_signatures: u16,
    pub price_per_signature: Lamports,
    pub compute_unit_limit: u32,
    pub prioritization_fee_rate: MicroLamports,
    pub blob_account_size: usize,
}

The expected fees for a blob upload, broken down by source.

Fields

num_signatures: u16

The number of signatures required, summed across all transactions.

price_per_signature: Lamports

The price per signature, in lamports. 5000 lamports by default.

compute_unit_limit: u32

The compute unit limit, summed across all transactions.

prioritization_fee_rate: MicroLamports

The prioritization fee rate, in micro-lamports.

blob_account_size: usize

The required size of the blober account, in bytes.

Implementations

impl Fee

pub const ZERO: Fee

pub fn static_fee(&self) -> Lamports

Calculate the static part of the fee for a blob upload. It is proportional to the number of signatures.

pub fn prioritization_fee(&self) -> Lamports

Calculate the recommended prioritization fee for a blob upload at the given priority. It is proportional to the compute unit limit, not the actual consumed compute units. The value is rounded up to the nearest lamport.

pub fn total_fee(&self) -> Lamports

Calculate the total fee for a blob upload, including the static fee and the prioritization fee. Does not include rent.

pub fn rent(&self) -> Lamports

Calculate the required rent used as a deposit for the blober account. Solana programs must hold on to a certain amount of lamports (SOL) in order to exist on-chain. This rent is paid upfront whenever an account is created or resized, and is proportional to the size of the account.

pub fn set_compute_unit_price(&self) -> Instruction

Creates a transaction for setting the compute unit price for a transaction.

Trait Implementations

impl Clone for Fee

fn clone(&self) -> Fee

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fee

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

Formats the value using the given formatter.

impl From<Fee> for FeeStrategy

fn from(fee: Fee) -> Self

Converts to this type from the input type.

impl Copy for Fee
