Struct fuchsia_pkg::MetaPackage

source ·
pub struct MetaPackage { /* private fields */ }
Expand description

A MetaPackage represents the “meta/package” file of a meta.far (which is a Fuchsia archive file of a Fuchsia package). It validates that the name and variant (called “version” in json) are valid.

Implementations§

source§

impl MetaPackage

source

pub const PATH: &'static str = "meta/package"

source

pub fn from_name_and_variant_zero(name: PackageName) -> Self

Create a MetaPackage with name and variant 0.

source

pub fn name(&self) -> &PackageName

Returns the package’s name.

source

pub fn variant(&self) -> &PackageVariant

Returns the package’s variant.

source

pub fn into_path(self) -> PackagePath

Convert into PackagePath.

source

pub fn deserialize(reader: impl BufRead) -> Result<Self, MetaPackageError>

Deserializes a MetaPackage from json.

§Examples
let json = r#"
    {"name": "package-name",
     "version": "0"}"#;
assert_eq!(
    MetaPackage::deserialize(json.as_bytes()).unwrap(),
    MetaPackage::from_name(
        "package-name".parse().unwrap(),
        "0".parse().unwrap(),
    )
);
source

pub fn serialize(&self, writer: impl Write) -> Result<(), MetaPackageError>

Serializes a MetaPackage to json.

§Examples
let meta_package = MetaPackage::from_name("package-name".parse().unwrap());
let mut v: Vec<u8> = vec![];
meta_package.serialize(&mut v).unwrap();
assert_eq!(std::str::from_utf8(v.as_slice()).unwrap(),
           r#"{"name":"package-name","version":"0"}"#);

impl PartialEq for MetaPackage

source§

fn eq(&self, other: &MetaPackage) -> bool
