Struct silkworm_sourcemap::Span

pub struct Span {
    pub base: u32,
    pub len: u32,
}

Fields

base: u32

len: u32

Implementations

impl Span

pub fn new(base: u32, len: u32) -> Self

pub fn nil() -> Self

Returns a Span { base: 0xFFFF_FFFF, len: 0 }. This is a special value that is reserved for invalid Spans.

pub fn is_nil(self) -> bool

Returns true if self is the nil span.

pub fn union(self, rhs: Span) -> Span

Returns the union between two spans.

Panics

If self or rhs is the nil span.

pub fn empty(self) -> Span

Returns an empty span at self.base.

pub fn read(self, source: &str, span_base: u32) -> &str

Returns the corresponding slice from source.

Panics

If the span is out=of-bounds for source.
