Struct tvix_build::proto::build_request::BuildConstraints

pub struct BuildConstraints {
    pub system: String,
    pub min_memory: u64,
    pub available_ro_paths: Vec<String>,
    pub network_access: bool,
    pub provide_bin_sh: bool,
}

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.

Fields

system: String

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

min_memory: u64

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

available_ro_paths: Vec<String>

A list of (absolute) paths that need to be available in the build environment, like /dev/kvm. This is distinct from the castore nodes in inputs. TODO: check if these should be individual constraints instead. These MUST be clean absolute paths, without any “.”, “..”, or superfluous slashes, and sorted.

network_access: bool

Whether the build should be able to access the network,

provide_bin_sh: bool

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 Default for BuildConstraints

fn default() -> Self

Returns the “default value” for a type.

impl Message for BuildConstraints

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

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.

impl TryFrom<BuildConstraints> for HashSet<BuildConstraints>

type Error = ValidateBuildConstraintsError

The type returned in the event of a conversion error.

fn try_from(value: BuildConstraints) -> Result<Self, Self::Error>

Performs the conversion.
