Enum tvix_build::buildservice::build_request::BuildConstraints

pub enum BuildConstraints {
    System(String),
    MinMemory(u64),
    AvailableReadOnlyPath(PathBuf),
    NetworkAccess,
    ProvideBinSh,
}

BuildConstraints represents certain conditions that must be fulfilled inside the build environment to be able to build this. Constraints can be things like required architecture and minimum amount of memory. The required input paths are not represented in here, because it wouldn’t be hermetic enough - see the comment around inputs too.

Variants

System(String)

The system that’s needed to execute the build. Must not be empty.

MinMemory(u64)

The amount of memory required to be available for the build, in bytes.

AvailableReadOnlyPath(PathBuf)

An absolute path that need to be available in the build environment, like /dev/kvm. This is distinct from the castore nodes in inputs. These MUST be clean absolute paths, without any “.”, “..”, or superfluous slashes, and sorted.

NetworkAccess

Whether the build should be able to access the network.

ProvideBinSh

Whether to provide a /bin/sh inside the build environment, usually a static bash.

Trait Implementations

impl Clone for BuildConstraints

fn clone(&self) -> BuildConstraints

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BuildConstraints

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

Formats the value using the given formatter.

impl Hash for BuildConstraints

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BuildConstraints

fn eq(&self, other: &BuildConstraints) -> 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.
