[−][src]Struct coreutils_core::os::utmp::UtmpSet
A collection of Utmp.
Methods
impl UtmpSet[src]
pub fn from_file(path: impl AsRef<Path>) -> Result<Self>[src]
Creates a new collection over a utmp entry binary file.
Errors
If a internal call set a errno (I/O OS error), an error variant will be returned.
pub fn system() -> Result<Self>[src]
Creates a new collection geting all entries from the running system.
Errors
If a internal call set a errno (I/O OS error), an error variant will be returned.
pub fn is_empty(&self) -> bool[src]
Returns true if collection nas no elements.
pub fn iter(&self) -> Iter<Utmp>[src]
Creates a iterator over it's entries.
