If the deleted profile is currently active, the active profile will be set to None.

Errors

This function will return an error if:

• The specified profile is not found
• The configuration cannot be saved to disk

pub fn list(&self) -> Vec<&Profile>

pub fn get(&self, name: &str) -> Option<&Profile>

pub fn get_mut(&mut self, name: &str) -> Option<&mut Profile>

pub fn active(&self) -> Option<&Profile>

pub fn switch(&mut self, name: &str) -> Result<()>

Switches to the specified profile, making it the active profile.

• The JSON data cannot be deserialized into a valid Profile
• The configuration cannot be saved to disk

pub fn save(&self) -> Result<()>
