Trait Implementations

impl CheckFillsUnalignedBits for AccountMetaFlags

type CheckType = [(); 1]

impl Clone for AccountMetaFlags

fn clone(&self) -> AccountMetaFlags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AccountMetaFlags

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

Formats the value using the given formatter.

impl Default for AccountMetaFlags

fn default() -> AccountMetaFlags

Returns the “default value” for a type.

impl PartialEq for AccountMetaFlags

fn eq(&self, other: &AccountMetaFlags) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
