Enum SemanticMode 

pub enum SemanticMode {
    HybridPreferred,
    LexicalOnly,
    StrictSemantic,
}

How aggressively cass pursues semantic search.

Variants

HybridPreferred

Default. Lexical always works; semantic blended in when available.

LexicalOnly

Lexical only — never build or consult semantic assets.

StrictSemantic

Both tiers required. Errors if semantic is unavailable.

Implementations

impl SemanticMode

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

pub fn parse(s: &str) -> Option<Self>

Parse from a user-provided string (env, CLI, config).

pub fn should_build_semantic(&self) -> bool

Whether semantic assets should be built at all.

pub fn requires_semantic(&self) -> bool

Whether search should fail if semantic is unavailable.

Trait Implementations

impl Clone for SemanticMode

fn clone(&self) -> SemanticMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SemanticMode

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

Formats the value using the given formatter.

impl Default for SemanticMode

fn default() -> SemanticMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SemanticMode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SemanticMode

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

Formats the value using the given formatter.

impl Hash for SemanticMode

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 SemanticMode

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for SemanticMode

impl Eq for SemanticMode

impl StructuralPartialEq for SemanticMode
