Struct AppData 

pub struct AppData {
    pub app_name: String,
    pub force_local: bool,
}

Examples

use app_data::AppData;

let app_data = AppData::default();

let app_data = AppData::new("my_app");

Fields

app_name: String

The name of the application, if the storage location is in the system application directory, use this application name as a subdirectory

中文说明

应用名称，如果存储位置在系统应用目录，以此应用名作为子目录

force_local: bool

Whether to force create the data directory under the startup path

中文说明

是否强制在运行目录下创建 data 目录

Implementations

impl AppData

Create a new AppData instance

pub fn new(app_name: &str) -> Self

pub fn with_force_local(app_name: &str, force_local: bool) -> Self

impl AppData

pub fn ensure_data_dir(&self) -> Result<PathBuf, AppDataError>

Return the application data directory according to the search rules, ensuring that the directory is valid and exists

Besides logging, you don’t need to care about this method, just keep track of the data file path

中文说明

按照寻找规则返回应用数据目录,会确保目录有效且存在。 除了记录日志，你并不需要关心此方法,保持关注数据文件路径即可

Examples

use app_data::AppData;

let app_data = AppData::default();
let data_dir = app_data.ensure_data_dir().unwrap();
println!("data_dir: {}", data_dir.display());

pub fn get_file_path(&self, file_name: &str) -> Result<PathBuf, AppDataError>

获取数据目录中的文件路径

Get the file path in the data directory

Examples

use app_data::AppData;

let app_data = AppData::new("my_app");
let file_path = app_data.get_file_path("config.json").unwrap();

Trait Implementations

impl Clone for AppData

fn clone(&self) -> AppData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AppData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AppData

fn default() -> Self

Default using CARGO_PKG_NAME as the application name, if CARGO_PKG_NAME is not set, then force_local is true

中文说明

默认使用 `CARGO_PKG_NAME` 作为应用名称，如果 `CARGO_PKG_NAME` 未设置，则`force_local` 为true

impl PartialEq for AppData

fn eq(&self, other: &AppData) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
