Enum BuildError 

pub enum BuildError {
    UnknownColumn(Box<str>),
    Unsupported(&'static str),
    Invalid(&'static str),
    UnknownTable(Box<str>),
    UnknownRelationship(Box<str>),
    Int64ColumnUnsupported {
        table: Box<str>,
        column: Box<str>,
    },
}

Errors raised while lowering an Ast into pipeline pieces (spec 08). Introduced for create_predicate; the build_pipeline spine grows it.

Variants

UnknownColumn(Box<str>)

A column name in the condition is not declared on the table Schema. (JS reads row[name] and silently gets undefined; the index-addressed engine needs the ColId, so a missing column is a hard build error.)

Unsupported(&'static str)

A condition shape the builder does not yet lower. The text is the reason — e.g. a flipped NOT EXISTS (anti-join) or an EXISTS subquery carrying a shape this builder cannot lower yet.

Invalid(&'static str)

A malformed condition: a literal’s type does not fit the operator — IN without an array, LIKE without a string pattern, a column on the RHS, or an ordering comparison between two mismatched literal types.

UnknownTable(Box<str>)

A table name in the AST has no registered source (resolve returned None).

UnknownRelationship(Box<str>)

A relationship alias is not declared on the parent table’s Schema.

Int64ColumnUnsupported

Design 226 §8 — the sync-boundary gate: the query’s footprint touches a declared int64 column, which the browser/room IVM value plane cannot carry until Stage E lands the bigint lane. The footprint is deliberately broader than the projection: a selected field, PK auto-inclusion, a predicate operand, a join/correlation key, an orderBy/grouping key, an aggregate input, or a paging-bound column all count. A query on the same table whose required-column set excludes the column stays admissible; the 222 SQL plane never enters build_pipeline and is unaffected.

Fields

table: Box<str>

column: Box<str>

Trait Implementations

impl Clone for BuildError

fn clone(&self) -> BuildError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuildError

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

Formats the value using the given formatter.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Error for BuildError

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 BuildError

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