Struct CustomSection

pub struct CustomSection {
    pub protection: CustomSectionProtection,
    pub alignment: Option<u64>,
    pub bytes: SectionBody,
    pub relocations: Vec<Relocation>,
}

Expand description

A Section for a Compilation.

This is used so compilers can store arbitrary information in the emitted module.

Fields§

§protection: CustomSectionProtection

Memory protection that applies to this section.

§alignment: Option<u64>

Alignment of this section. When missing, the default value for each platform shall be used.

§bytes: SectionBody

The bytes corresponding to this section.

Note: These bytes have to be at-least 8-byte aligned (the start of the memory pointer). We might need to create another field for alignment in case it’s needed in the future.

§relocations: Vec<Relocation>

Relocations that apply to this custom section.

Trait Implementations§
