Struct BranchSpec

pub struct BranchSpec { /* private fields */ }

Represents a branch: a list of (branchpoint, branch value) pairs. If a branch has the NULL_IDENT IdentId, that means it is a baseline branch. Baseline can mean either that the branch was unspecified, or that it was specifically intended to be baseline, depending on the use case. This ambiguity is something we should clean up eventually.

Implementations

impl BranchSpec

pub fn simple(k: BranchpointId, v: IdentId) -> Self

Create a new branch with the given branchpoint/branch pair.

pub fn insert(&mut self, k: BranchpointId, v: IdentId)

Insert the given branchpoint/branch pair into this BranchSpec.

pub fn get_specified(&self, k: BranchpointId) -> Option<IdentId>

Get the branch id if it is specified/non-baseline, otherwise None.

pub fn is_unspecified(&self, k: BranchpointId) -> bool

true if branchpoint k is unspecified/baseline.

pub fn is_specified(&self, k: BranchpointId) -> bool

true if branchpoint k is specified/non-baseline.

pub fn unset(&mut self, k: BranchpointId)

remove branch info for branchpoint k, leaving it unspecified/baseline.

pub fn iter(&self) -> impl Iterator<Item = &IdentId>

Iterate through branchpoints

pub fn len(&self) -> usize

Length of the underlying vec.

pub fn is_empty(&self) -> bool

True if len == 0.

pub fn is_compatible(&self, other: &Self) -> bool

true if all specified branches in this branch match with other branch; allowing any unspecified branches here to still count as a match.

pub fn is_exact_match(&self, other: &Self) -> bool

true if all specified branches in this branch exactly match other branch.

pub fn insert_all(&mut self, other: &Self)

Insert all defined branches from other into self.

impl BranchSpec

pub fn as_mask<T>(&self) -> Result<T, Error>

where T: Bitmask + Default,

Trait Implementations

impl Clone for BranchSpec

fn clone(&self) -> BranchSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BranchSpec

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

Formats the value using the given formatter.

impl Default for BranchSpec

fn default() -> BranchSpec

Returns the “default value” for a type.

impl Hash for BranchSpec

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BranchSpec

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