Implementations

impl PkgConfig

pub fn open(path: &Path) -> Result<Self, OpenError>

pub fn from_bytes(bytes: &[u8]) -> Result<Self, ParseError>

Read a pkg-config .pc file from a byte slice

pub fn libs(&self) -> Result<Links, VariableError>

Get an iterator over the items in the Libs key

pub fn libs_private(&self) -> Result<Links, VariableError>

Get an iterator over the items in the Libs.private key

pub fn variable(&self, var: impl AsRef<[u8]>) -> Option<&[u8]>

Get a variable

pub fn set_variable( &mut self, var: impl AsRef<[u8]>, value: impl AsRef<[u8]>, allow_overwrite: bool, ) -> bool

Set a variable

pub fn set_variable_escaped( &mut self, var: impl AsRef<[u8]>, value: impl AsRef<[u8]>, allow_overwrite: bool, ) -> bool

Set a variable and escape it

pub fn expand_variable( &self, var: impl AsRef<[u8]>, ) -> Result<Vec<u8>, VariableError>

Get a variable and expand all variables it references

pub fn expand_variables_in( &self, input: impl AsRef<[u8]>, ) -> Result<Vec<u8>, VariableError>

Expand all variables in the input

pub fn key_bytes(&self, key: impl AsRef<[u8]>) -> Option<&[u8]>

Get the raw bytes of a key

pub fn key_bytes_expanded( &self, key: impl AsRef<[u8]>, ) -> Result<Option<Vec<u8>>, VariableError>

Get the raw bytes of a key with variables expanded

pub fn key_bytes_expanded_unescaped_split( &self, key: impl AsRef<[u8]>, ) -> Result<Option<UnescapeAndSplit>, VariableError>

Get the raw bytes of a key with variables expanded, unescaped and split by spaces
