Enum AppMode 

pub enum AppMode {
    Development,
    Production,
}

Controls how the framework behaves at startup and at runtime.

Variants

Development

Full startup banner, per-request console logging, verbose diagnostics.

Production

Minimal one-line startup message, no framework-initiated console logging.

Implementations

impl AppMode

pub fn overlay_filename(&self) -> &'static str

环境模式对应的 overlay 文件名，如 appsettings.Development.json。

pub fn from_env() -> AppMode

从环境变量 APP_ENV 解析运行模式；未设置或值非法时返回 Development。

接受（不区分大小写）：Production / Prod / Development / Dev。

pub fn from_env_var(var: &str) -> AppMode

从指定环境变量名解析运行模式。

Trait Implementations

impl Clone for AppMode

fn clone(&self) -> AppMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AppMode

impl Debug for AppMode

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

Formats the value using the given formatter.

impl Default for AppMode

fn default() -> AppMode

Returns the “default value” for a type.

impl Eq for AppMode

impl PartialEq for AppMode

fn eq(&self, other: &AppMode) -> 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.
