Struct MutationPreconditions 

pub struct MutationPreconditions { /* private fields */ }

Conditional revisions captured when a mutation intent is created.

Implementations

impl MutationPreconditions

pub const fn new( metadata_revision: Option<MetadataRevision>, content_revision: Option<ContentRevision>, ) -> Self

Creates independent metadata and content revision preconditions.

pub const fn metadata_revision(&self) -> Option<&MetadataRevision>

Returns the expected metadata revision, when one is required.

pub const fn content_revision(&self) -> Option<&ContentRevision>

Returns the expected content revision, when one is required.

Trait Implementations

impl Clone for MutationPreconditions

fn clone(&self) -> MutationPreconditions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MutationPreconditions

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

Formats the value using the given formatter.

impl Default for MutationPreconditions

fn default() -> MutationPreconditions

Returns the “default value” for a type.

impl PartialEq for MutationPreconditions

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