Struct Dependency

pub struct Dependency { /* private fields */ }

Implementations

impl Dependency

pub fn get_all() -> Result<Vec<Dependency>>

pub fn replace_all<'a>( dependencies: impl Iterator<Item = (Option<&'a DownloadedBottle>, &'a DownloadedBottle)>, ) -> Result<()>

pub fn dependent(&self) -> Result<Option<DownloadedBottle>>

Returns None if the bottle was manually added, i.e. if it is a root.

pub fn dependent_id(&self) -> Option<i32>

pub fn dependency(&self) -> Result<DownloadedBottle>

pub fn dependency_id(&self) -> i32
