Enum NextjsRenderEnvironment 

pub enum NextjsRenderEnvironment {
    ServerComponent,
    ClientSsr,
    ClientHydrated,
    EdgeRuntime,
    NodeServer,
}

Next.js rendering environment where a component executes.

Determines what capabilities are available. The WASM runtime is only usable in ClientComponent after hydration.

Variants

ServerComponent

Server Component — no WASM, no browser APIs, no state/effects.

ClientSsr

Client Component during SSR pass — no WASM, limited browser APIs.

ClientHydrated

Client Component after hydration — full WASM and browser APIs.

EdgeRuntime

Edge Runtime — no WASM, limited Node APIs.

NodeServer

Node.js API route / Server Action — no WASM, full Node APIs.

Implementations

impl NextjsRenderEnvironment

pub fn supports_wasm_runtime(self) -> bool

Returns true if this environment supports WASM runtime initialization.

pub fn has_browser_apis(self) -> bool

Returns true if browser APIs (DOM, fetch with credentials, etc.) are available.

pub fn is_server_side(self) -> bool

Returns true if this is a server-side environment.

pub fn boundary_mode(self) -> NextjsBoundaryMode

Returns the normalized boundary mode for this environment.

pub fn runtime_fallback(self) -> NextjsRuntimeFallback

Returns deterministic fallback behavior when runtime capability is unavailable.

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

Human-readable fallback guidance for diagnostics and docs.

Trait Implementations

impl Clone for NextjsRenderEnvironment

fn clone(&self) -> NextjsRenderEnvironment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NextjsRenderEnvironment

impl Debug for NextjsRenderEnvironment

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NextjsRenderEnvironment

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for NextjsRenderEnvironment

impl Hash for NextjsRenderEnvironment

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NextjsRenderEnvironment

fn eq(&self, other: &NextjsRenderEnvironment) -> 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 NextjsRenderEnvironment

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
