Enum MsrvSource 

pub enum MsrvSource {
    Deps,
    Workspace,
    Max,
}

How to determine the final MSRV (Minimum Supported Rust Version)

Controls how cargo-rail computes the rust-version to write to [workspace.package].

Variants

Deps

Use maximum from dependencies only (original behavior)

Computes the highest rust-version from all resolved dependencies. Overwrites any existing workspace rust-version.

Workspace

Preserve existing workspace rust-version

Keeps the existing [workspace.package].rust-version unchanged. Emits a warning if dependencies require a higher version.

Max

Take max(workspace, deps) - default

Uses the higher of the existing workspace rust-version or the maximum from dependencies. Your explicit workspace setting wins if it requires a higher Rust version than your dependencies.

Trait Implementations

impl Clone for MsrvSource

fn clone(&self) -> MsrvSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MsrvSource

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

Formats the value using the given formatter.

impl Default for MsrvSource

fn default() -> MsrvSource

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MsrvSource

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MsrvSource

fn eq(&self, other: &MsrvSource) -> 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 MsrvSource

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for MsrvSource

impl Eq for MsrvSource
