Implementations

impl Reader

pub fn from_build_dir<P: AsRef<Path>>(build_dir: P) -> Result<Self, ReaderError>

Create a new reader from a build directory

Errors

ReaderError::FileApiNotGenerated: if the cmake-file-api is not generated for the build directory ReaderError::IO: if an IO error occurs while reading the index file ReaderError::Parse: if an error occurs while parsing the index file

pub fn build_dir(&self) -> &Path

pub fn index(&self) -> &Index

pub fn has_object<T: Object>(&self) -> bool

pub fn read_object<T: Object + DeserializeOwned>( &self, ) -> Result<T, ReaderError>

read object

Errors

ReaderError::ObjectNotFound: if the index file does not contain the requested object ReaderError::IO: if an IO error occurs while reading the object file ReaderError::Parse: if an error occurs while parsing the object file
