Struct EnvVar

pub struct EnvVar {
    pub name: String,
    pub value: Option<String>,
    pub value_from: Option<EnvVarSource>,
}

EnvVar represents an environment variable present in a Container.

Fields

name: String

Name of the environment variable. Must be a C_IDENTIFIER.

value: Option<String>

Variable references $(VAR_NAME) are expanded using the previously defined environment variables in the container and any service environment variables. If a variable cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. “$$(VAR_NAME)” will produce the string literal “$(VAR_NAME)”. Escaped references will never be expanded, regardless of whether the variable exists or not. Defaults to “”.

value_from: Option<EnvVarSource>

Source for the environment variable’s value. Cannot be used if value is not empty.

Trait Implementations

impl Clone for EnvVar

fn clone(&self) -> EnvVar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EnvVar

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

Formats the value using the given formatter.

impl DeepMerge for EnvVar

fn merge_from(&mut self, other: Self)

Merge other into self.

impl Default for EnvVar

fn default() -> EnvVar

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EnvVar

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EnvVar

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

impl Serialize for EnvVar

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
