Enum GuideError 

pub enum GuideError {
    UnsupportedDiscreteLatent {
        addr: Address,
        value_type: &'static str,
    },
}

Error returned when a guide cannot be constructed for a model latent.

The mean-field guide families implemented here (VariationalParam) are all continuous. A discrete latent (Bool / U64 / Usize / I64) has no continuous variational factor, so guide construction returns this typed error instead of silently emitting an f64 factor (which would later panic when scored against the discrete model site) — see finding FG-17.

Variants

UnsupportedDiscreteLatent

A discrete latent was encountered where only continuous latents are supported.

Fields

addr: Address

Address of the offending latent.

value_type: &'static str

The ChoiceValue type name of the discrete latent (e.g. "bool").

impl Error for GuideError

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
