Trait simple_parse::SpOptHints

pub unsafe trait SpOptHints {
    const IS_VAR_SIZE: bool;
    const STATIC_SIZE: usize;
    const COUNT_SIZE: usize;
}

Provides optimization hints used by SpRead traits.

Safety

When not using defaults, implementors must be very careful not to return invalid values as it may lead to buffer over reads (e.g. setting STATIC_SIZE to 4 and reading 8 bytes in the unchecked readers)

Associated Constants

const IS_VAR_SIZE: bool

Whether the type has a variable size

const STATIC_SIZE: usize

How many bytes the unchecked parsing functions can assume are valid

const COUNT_SIZE: usize

Used to substract from STATIC_SIZE when a count is provided
