Enum OptionsUpdateEnvValueMode 

pub enum OptionsUpdateEnvValueMode {
    Direct,
    Indirect,
    Unknown,
}

How env values are passed to MCP servers (direct inlines literal values; indirect resolves at launch).

Experimental. This type is part of an experimental wire-protocol surface and may change or be removed in future SDK or CLI releases.

Variants

Direct

Pass MCP server environment values as literal strings.

Indirect

Resolve MCP server environment values from host-side references.

Unknown

Unknown variant for forward compatibility.

Trait Implementations

impl Clone for OptionsUpdateEnvValueMode

fn clone(&self) -> OptionsUpdateEnvValueMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionsUpdateEnvValueMode

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

Formats the value using the given formatter.

impl Default for OptionsUpdateEnvValueMode

fn default() -> OptionsUpdateEnvValueMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OptionsUpdateEnvValueMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for OptionsUpdateEnvValueMode

impl PartialEq for OptionsUpdateEnvValueMode

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
