Expand description
A Compute Config Store.
Implementations§
Source§impl ConfigStore
impl ConfigStore
Sourcepub fn open(name: &str) -> Self
pub fn open(name: &str) -> Self
Open a config store, given its name.
§Examples
let merriam = ConfigStore::open("merriam webster");
let oed = ConfigStore::open("oxford english config store");
Sourcepub fn try_open(name: &str) -> Result<Self, OpenError>
pub fn try_open(name: &str) -> Result<Self, OpenError>
Try to open a config store, given its name.
§Examples
let merriam = ConfigStore::try_open("merriam webster").unwrap();
Sourcepub fn get(&self, key: &str) -> Option<String>
pub fn get(&self, key: &str) -> Option<String>
Lookup a value in this config store.
If successful, this function returns Some(_)
if an entry was found, or None
if no entry
with the given key was found.
§Examples
assert_eq!(
config_store.get("bread"),
Some(String::from("a usually baked and leavened food")),
);
assert_eq!(
config_store.get("freedom"),
Some(String::from("the absence of necessity, coercion, or constraint")),
);
// Otherwise, `get` will return nothing.
assert!(config_store.get("zzzzz").is_none());
§Panics
This may panic for any of the reasons that ConfigStore::try_get
would return an error.
Sourcepub fn try_get(&self, key: &str) -> Result<Option<String>, LookupError>
pub fn try_get(&self, key: &str) -> Result<Option<String>, LookupError>
Try to lookup a value in this Config Store.
If successful, this function returns Ok(Some(_))
if an entry was found, or Ok(None)
if
no entry with the given key was found. This function returns Err(_)
if the lookup failed.
§Examples
assert_eq!(
config_store.try_get("bread").unwrap(),
Some(String::from("a usually baked and leavened food")),
);
assert_eq!(
config_store.try_get("freedom").unwrap(),
Some(String::from("the absence of necessity, coercion, or constraint")),
);
// Otherwise, `try_get` will return nothing.
assert!(config_store.try_get("zzzzz").unwrap().is_none());
