Struct ToolchainLockfile 

pub struct ToolchainLockfile {
    pub schema: u32,
    pub generated_at: String,
    pub tools: Vec<LockedTool>,
}

The parsed toolchain lockfile: a schema tag, a generation timestamp, and the set of pinned tools (serialized as a TOML [[tool]] array of tables).

Fields

schema: u32

On-disk schema version (see TOOLCHAIN_LOCK_SCHEMA).

generated_at: String

RFC 3339 timestamp of when the lock was last written.

tools: Vec<LockedTool>

The pinned tools. Serialized/deserialized as [[tool]] tables.

Trait Implementations

impl Clone for ToolchainLockfile

fn clone(&self) -> ToolchainLockfile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolchainLockfile

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToolchainLockfile

fn deserialize<__D>( __deserializer: __D, ) -> Result<ToolchainLockfile, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ToolchainLockfile

impl PartialEq for ToolchainLockfile

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ToolchainLockfile

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for ToolchainLockfile

impl ToolchainLockfileExt for ToolchainLockfile

fn new() -> Self

A fresh, empty lockfile stamped with the current schema + timestamp.

fn load(path: &Path) -> Result<Option<Self>>

Load a lockfile from path.

fn save(&self, path: &Path) -> Result<()>

Serialize to TOML at path with a stable (tool, platform, arch) order.

fn lookup(&self, tool: &str, platform: &str, arch: &str) -> Option<&LockedTool>

The pinned entry for (tool, platform, arch), if present.

fn upsert(&mut self, entry: LockedTool)

Insert entry, replacing any existing pin for its (tool, platform, arch).
