[−][src]Enum cranelift_codegen::settings::detail::Detail

pub enum Detail {
    Bool {
        bit: u8,
    },
    Num,
    Enum {
        last: u8,
        enumerators: u16,
    },
    Preset,
}

The different kind of settings along with descriptor bits that depend on the kind.

Variants

Bool

A boolean setting only uses one bit, numbered from LSB.

Fields of Bool

bit: u8

0-7.

Num

A numerical setting uses the whole byte.

Enum

An Enum setting uses a range of enumerators.

Fields of Enum

last: u8

Numerical value of last enumerator, allowing for 1-256 enumerators.

enumerators: u16

First enumerator in the ENUMERATORS table.

Preset

A preset is not an individual setting, it is a collection of settings applied at once.

The Descriptor::offset field refers to the PRESETS table.

Methods

impl Detail[src]

pub fn is_preset(self) -> bool[src]

Check if a detail is a Detail::Preset. Useful because the Descriptor offset field has a different meaning when the detail is a preset.
