Struct polkavm_common::elf::ImportMetadata

pub struct ImportMetadata<'a> {
    pub hash: [u8; 16],
    pub index: Option<u32>,
    pub prototype: FnMetadata<'a>,
}

Import metadata. Serialized by the derive macro and deserialized when relinking the ELF file.

Fields

hash: [u8; 16]

index: Option<u32>

prototype: FnMetadata<'a>

Implementations

impl<'a> ImportMetadata<'a>

pub fn args(&self) -> impl Iterator<Item = ExternTy> + '_

pub fn return_ty(&self) -> Option<ExternTy>

pub fn name(&self) -> &str

pub fn serialize(&self, cb: impl FnMut(&[u8]))

pub fn try_deserialize(b: &'a [u8]) -> Result<(usize, Self), &'static str>

Trait Implementations

impl<'a> Clone for ImportMetadata<'a>

fn clone(&self) -> ImportMetadata<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ImportMetadata<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> PartialEq<ImportMetadata<'a>> for ImportMetadata<'a>

fn eq(&self, other: &ImportMetadata<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
