Enum CaseTree 

pub enum CaseTree {
    Leaf {
        body_idx: usize,
    },
    Switch {
        scrutinee: usize,
        branches: Vec<CaseBranch>,
        default: Option<Box<CaseTree>>,
    },
    Failure,
}

Result of pattern compilation.

Variants

Leaf

A leaf node: execute the body at the given index

Fields

body_idx: usize

Index into the original clause list

Switch

A switch on a scrutinee column

Fields

scrutinee: usize

Column index of the scrutinee

branches: Vec<CaseBranch>

Constructor branches

default: Option<Box<CaseTree>>

Default branch if no constructor matches

Failure

Pattern match failure (non-exhaustive)

Trait Implementations

impl Clone for CaseTree

fn clone(&self) -> CaseTree

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CaseTree

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

Formats the value using the given formatter.

impl PartialEq for CaseTree

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