Enum Capability 

#[repr(u8)]
pub enum Capability {
    ReadsState = 0,
    MutatesState = 1,
    TouchesJournal = 2,
    ExternalCall = 3,
    MutatesTreasury = 4,
    ReallocatesAccount = 5,
    CreatesAccount = 6,
    ClosesAccount = 7,
    ModifiesAuthority = 8,
    TransitionsState = 9,
}

Instruction capability flags.

Each capability is a single bit in a u32 bitmask. Programs declare which capabilities an instruction requires.

Variants

ReadsState = 0

Instruction reads owned account data.

MutatesState = 1

Instruction mutates owned account data.

TouchesJournal = 2

Instruction writes to a journal segment.

ExternalCall = 3

Instruction calls another program via CPI.

MutatesTreasury = 4

Instruction modifies treasury/vault balances.

ReallocatesAccount = 5

Instruction performs account reallocation.

CreatesAccount = 6

Instruction creates a new account.

ClosesAccount = 7

Instruction closes an account.

ModifiesAuthority = 8

Instruction modifies permissions/authority.

TransitionsState = 9

Instruction triggers a state machine transition.

Implementations

impl Capability

pub const fn mask(self) -> u32

Convert to bitmask.

impl Capability

Capability name lookup.

pub const fn name(self) -> &'static str

Human-readable name for this capability.

Trait Implementations

impl Clone for Capability

fn clone(&self) -> Capability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl PartialEq for Capability

fn eq(&self, other: &Capability) -> 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 Copy for Capability

impl Eq for Capability

impl StructuralPartialEq for Capability
