Struct Built 

pub struct Built { /* private fields */ }

The validated Built element of package metadata.

Unlike PackageMeta::description_field, whose nested Option distinguishes an absent field from a present R NA, the optional accessors here deliberately collapse both cases to None: for build metadata, an absent Platform and an NA Platform carry the same meaning to consumers (“no usable value”), so the distinction is not preserved.

Implementations

impl Built

pub fn r_version(&self) -> &PackageVersion

pub fn date(&self) -> Option<&str>

Returns the build date, if it is present and not NA.

pub fn os_type(&self) -> Option<&str>

Returns the operating-system type, if it is present and not NA.
