Enum scroll::ctx::StrCtx

source · [−]

pub enum StrCtx {
    Delimiter(u8),
    DelimiterUntil(u8, usize),
    Length(usize),
}

Expand description

The parsing context for converting a byte sequence to a &str

StrCtx specifies what byte delimiter to use, and defaults to C-style null terminators. Be careful.

Variants

`Delimiter(u8)`

`DelimiterUntil(u8, usize)`

`Length(usize)`
