Enum TemplateError 

pub enum TemplateError {
    PlaceholderMissing(String),
    PlaceholderUnknown(String),
    InjectionDetected {
        slot: String,
        reason: String,
    },
    SecretLeakBlocked {
        pattern: String,
    },
    OversizeContext {
        bytes: usize,
        max: usize,
    },
}

Failures from PromptTemplate::render. Every variant carries enough detail for the audit log without echoing the offending payload — reason strings are bounded to a short categorical label, never the raw input.

Variants

PlaceholderMissing(String)

A {placeholder} in the template body has no slot to fill it.

PlaceholderUnknown(String)

A {placeholder} slot was supplied that the template body does not reference. Surfaces drift between operator template and runtime caller.

InjectionDetected

Injection signal detected in a slot. slot names the slot category; reason is a short label (role_flip/placeholder_breakout/json_breakout/…). The offending payload is not included.

Fields

slot: String

reason: String

SecretLeakBlocked

A secret-shaped pattern was found in a slot category that is not allowed to carry one. The pattern name is included; the matched bytes are not.

Fields

pattern: String

OversizeContext

Rendered total exceeded the per-tier byte cap.

Fields

bytes: usize

max: usize

Trait Implementations

impl Clone for TemplateError

fn clone(&self) -> TemplateError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TemplateError

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

Formats the value using the given formatter.

impl Display for TemplateError

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

Formats the value using the given formatter.

impl Error for TemplateError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for TemplateError

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