sourcepub fn load(&self, key: &[u8]) -> Result<T, StdError>
pub fn load(&self, key: &[u8]) -> Result<T, StdError>
load will return an error if no data is set at the given key, or on parse error
sourcepub fn may_load(&self, key: &[u8]) -> Result<Option<T>, StdError>
pub fn may_load(&self, key: &[u8]) -> Result<Option<T>, StdError>
may_load will parse the data stored at the key if present, returns Ok(None) if no data there. returns an error on issues parsing
