Enum Unit 

pub enum Unit<'a> {
    TokenWithRange(&'a TokenWithRange<'a>),
    RandomBlock {
        value: SourceRangeMixin<BlockValue>,
        if_blocks: Vec<IfBlock<'a>>,
        end_random: SourceRangeMixin<()>,
    },
    SwitchBlock {
        value: SourceRangeMixin<BlockValue>,
        cases: Vec<CaseBranch<'a>>,
        end_sw: SourceRangeMixin<()>,
    },
}

An unit of AST which represents individual scoped commands of BMS source.

Variants

TokenWithRange(&'a TokenWithRange<'a>)

A token that is not a control flow token.

RandomBlock

A Random block. Can contain multiple If blocks.

Fields

value: SourceRangeMixin<BlockValue>

The value of the Random block.

if_blocks: Vec<IfBlock<'a>>

The If blocks in the Random block.

end_random: SourceRangeMixin<()>

The ENDRANDOM position in the BMS source.

SwitchBlock

A Switch block. Like C++ Programming Language, Switch block can contain multiple Case branches, and a Def branch. If there is no other Case branch activated, Def branch will be activated. When executing, the tokens, from the activated branch, to Skip/EndSwitch, will be executed.

Fields

value: SourceRangeMixin<BlockValue>

The value of the Switch block.

cases: Vec<CaseBranch<'a>>

The Case branches in the Switch block.

end_sw: SourceRangeMixin<()>

The ENDSW position in the BMS source.

Trait Implementations

impl<'a> Clone for Unit<'a>

fn clone(&self) -> Unit<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Unit<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Unit<'a>

fn eq(&self, other: &Unit<'a>) -> 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.
