DataObj

Struct DataObj 

Source
pub struct DataObj<'parent> { /* private fields */ }
Expand description

A smart pointer to obs_data_t

Implementations§

Source§

impl DataObj<'_>

Source

pub fn new() -> Self

Creates a empty data object

Source

pub fn from_json(json_str: impl Into<ObsString>) -> Option<Self>

Loads data into a object from a JSON string.

Source

pub fn from_json_file( json_file: impl Into<ObsString>, backup_ext: impl Into<Option<ObsString>>, ) -> Option<Self>

Loads data into a object from a JSON file.

  • backup_ext: optional backup file path in case the original file is bad.
Source

pub fn get<T: FromDataItem>(&self, name: impl Into<ObsString>) -> Option<T>

Fetches a property from this object. Numbers are implicitly casted.

Source

pub fn set_default<T: FromDataItem>( &mut self, name: impl Into<ObsString>, value: impl Into<T>, )

Sets a default value for the key.

§Notes

Setting a default value for a DataArray is not supported and will panic.

Source

pub fn get_json(&self) -> Option<String>

Creates a JSON representation of this object.

Source

pub fn clear(&mut self)

Clears all values.

Source

pub fn remove(&mut self, name: impl Into<ObsString>)
