Struct cargo_component_core::lock::LockFile

pub struct LockFile {
    pub version: i64,
    pub packages: Vec<LockedPackage>,
}

Represents a resolved dependency lock file.

This is a TOML file that contains the resolved dependency information from a previous build.

Fields

version: i64

The version of the lock file.

Currently this is always 1.

packages: Vec<LockedPackage>

The locked dependencies in the lock file.

This list is sorted by the key of the locked package.

Implementations

impl LockFile

pub fn new(packages: impl Into<Vec<LockedPackage>>) -> Self

Constructs a new lock file from a list of locked packages.

It is expected that the packages will be already sorted.

pub fn read(file: &File) -> Result<Self>

Reads the lock file from the given file object.

pub fn write(&self, file: &File, app: &str) -> Result<()>

Writes the lock file to the given file object.

The app name is used to generate a header comment.

Trait Implementations

impl Clone for LockFile

fn clone(&self) -> LockFile

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LockFile

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

Formats the value using the given formatter.

impl Default for LockFile

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LockFile

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LockFile

fn eq(&self, other: &LockFile) -> 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 Serialize for LockFile

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
