Struct lucet_module::VersionInfo

#[repr(C)]
pub struct VersionInfo { /* fields omitted */ }

VersionInfo is information about a Lucet module to allow the Lucet runtime to determine if or how the module can be loaded, if so requested. The information here describes implementation details in runtime support for lucetc-produced modules, and nothing higher level.

Methods

impl VersionInfo

pub fn new(
    major: u16,
    minor: u16,
    patch: u16,
    version_hash: [u8; 8]
) -> VersionInfo

pub fn compatible_with(&self, other: &VersionInfo) -> bool

A more permissive version check than for version equality. This check will allow an other version that is more specific than self, but matches for data that is available.

pub fn write_to<W: WriteBytesExt>(&self, w: &mut W) -> Result<()>

pub fn read_from<R: ReadBytesExt>(r: &mut R) -> Result<Self>

pub fn valid(&self) -> bool

pub fn current(current_hash: &'static [u8]) -> Self
