Struct cargo::ops::common_for_install_and_uninstall::InstallInfo

struct InstallInfo {
    version_req: Option<String>,
    bins: BTreeSet<String>,
    features: BTreeSet<String>,
    all_features: bool,
    no_default_features: bool,
    profile: String,
    target: Option<String>,
    rustc: Option<String>,
    other: BTreeMap<String, Value>,
}

Tracking information for the installation of a single package.

This tracks the settings that were used when the package was installed. Future attempts to install the same package will check these settings to determine if it needs to be rebuilt/reinstalled. If nothing has changed, then Cargo will inform the user that it is “up to date”.

This is only used for the v2 format.

Fields

version_req: Option<String>

Version requested via --version. None if --version not specified. Currently not used, possibly may be used in the future.

bins: BTreeSet<String>

Set of binary names installed.

features: BTreeSet<String>

Set of features explicitly enabled.

all_features: bool

no_default_features: bool

profile: String

Either “debug” or “release”.

target: Option<String>

The installation target. Either the host or the value specified in --target. None if unknown (when loading from v1).

rustc: Option<String>

Output of rustc -V. None if unknown (when loading from v1). Currently not used, possibly may be used in the future.

other: BTreeMap<String, Value>

Forwards compatibility.

Implementations

impl InstallInfo

fn from_v1(set: &BTreeSet<String>) -> InstallInfo

fn is_up_to_date( &self, opts: &CompileOptions, target: &str, exes: &BTreeSet<String> ) -> bool

Determine if this installation is “up to date”, or if it needs to be reinstalled.

This does not do Package/Source/Version checking.

Trait Implementations

impl Debug for InstallInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InstallInfo

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

Deserialize this value from the given Serde deserializer.

impl Serialize for InstallInfo

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

Serialize this value into the given Serde serializer.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
