Enum sway_core::parse_tree::declaration::function::Purity

pub enum Purity {
    Pure,
    Reads,
    Writes,
    ReadsWrites,
}

The purity of a function is related to its access of contract storage. If a function accesses or could potentially access contract storage, it is [Purity::Impure]. If a function does not utilize any any accesses (reads or writes) of storage, then it is Purity::Pure.

Trait Implementations

impl Clone for Purity

fn clone(&self) -> Purity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Purity

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

Formats the value using the given formatter.

impl Default for Purity

fn default() -> Self

Returns the “default value” for a type.

impl Hash for Purity

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<Purity> for Purity

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