Implementations§

source§

impl Block

source

pub fn new(block: mrb_value) -> Option<Self>

Construct a Block from a Ruby value.

source

pub const unsafe fn new_unchecked(block: mrb_value) -> Self

pub const fn inner(&self) -> mrb_value

source

pub fn yield_arg(
    &self,
    interp: &mut Artichoke,
    arg: &Value
) -> Result<Value, Error>
