Struct OptionsCollection 

pub struct OptionsCollection {
    pub options: Vec<OptionInfo>,
}

An owned snapshot of every option in a cpdb_options_t.

Fields

options: Vec<OptionInfo>

Every option discovered.

Implementations

impl OptionsCollection

pub unsafe fn from_raw(raw: *mut cpdb_options_t) -> Result<Self>

Builds an OptionsCollection by iterating raw.table.

Safety

raw must be either null or a valid pointer to a fully initialised cpdb_options_t whose table field is a valid GHashTable*.

pub fn len(&self) -> usize

Returns the number of options in this collection.

pub fn is_empty(&self) -> bool

Returns true if this collection has no options.

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

Finds an option by name (linear search).

pub fn iter(&self) -> impl Iterator<Item = &OptionInfo>

Returns an iterator over all options.
