Struct TransactionConfigMask 

pub struct TransactionConfigMask(pub u32);

Available on non-target_os=solana only.

Bitmask indicating which configuration values are present in a V1 transaction.

Each bit (or bit pair) corresponds to a specific configuration field. The config values array contains entries only for fields whose bits are set.

Tuple Fields

0: u32

Implementations

impl TransactionConfigMask

pub const PRIORITY_FEE: u32 = 0b11

Mask for priority fee config.

Bits 0-1 (requires both bits set, 8 bytes as u64 LE).

pub const COMPUTE_UNIT_LIMIT: u32 = 0b100

Mask for compute unit limit

Bit 2 (4 bytes as u32 LE).

pub const LOADED_ACCOUNTS_DATA_SIZE: u32 = 0b1000

Mask for loaded accounts data size limit

Bit 3 (4 bytes as u32 LE).

pub const HEAP_SIZE: u32 = 0b10000

Mask for requested heap size.

Bit 4 (4 bytes as u32 LE).

pub const KNOWN_BITS: u32

Mask of all known/supported bits (bits 0-4).

pub const fn new(mask: u32) -> Self

pub const fn has_unknown_bits(&self) -> bool

Returns `true`` if any unknown bits are set.

An unknown bit is any bit that is not defined in KNOWN_BITS.

pub const fn has_priority_fee(&self) -> bool

pub const fn has_invalid_priority_fee_bits(&self) -> bool

Returns true if only one of the two priority fee bits is set (invalid).

pub const fn has_compute_unit_limit(&self) -> bool

pub const fn has_loaded_accounts_data_size(&self) -> bool

pub const fn has_heap_size(&self) -> bool

pub const fn size_of_config(&self) -> usize

Total size in bytes required to store the config values.

Trait Implementations

impl AbiExample for TransactionConfigMask

fn example() -> Self

impl Clone for TransactionConfigMask

fn clone(&self) -> TransactionConfigMask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionConfigMask

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

Formats the value using the given formatter.

impl Default for TransactionConfigMask

fn default() -> TransactionConfigMask

Returns the “default value” for a type.

impl From<&TransactionConfig> for TransactionConfigMask

fn from(config: &TransactionConfig) -> Self

Converts to this type from the input type.

impl From<TransactionConfig> for TransactionConfigMask

fn from(config: TransactionConfig) -> Self

Converts to this type from the input type.

impl PartialEq for TransactionConfigMask

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