Struct KeyState 

pub struct KeyState {
    pub seen_int: bool,
    pub seen_float: bool,
    pub seen_bool: bool,
    pub seen_time: bool,
    pub seen_binary_hex: bool,
    pub seen_string: bool,
    pub seen_null: bool,
    pub total_records_seen_in: usize,
    pub present_count: usize,
    pub first_sigil: Option<u8>,
}

Per-key state maintained during pass 1.

Fields

seen_int: bool

seen_float: bool

seen_bool: bool

seen_time: bool

seen_binary_hex: bool

seen_string: bool

seen_null: bool

total_records_seen_in: usize

present_count: usize

Records in which this key was present (non-null).

first_sigil: Option<u8>

Sigil from the very first non-null observation (for FirstWins policy).

Implementations

impl KeyState

pub fn observe(&mut self, raw: &str)

Classify a raw string observation and merge into self.

pub fn resolve_sigil(&self, policy: ConflictPolicy) -> Result<u8>

Collapse accumulated flags to a single sigil byte per plan priority.

Trait Implementations

impl Clone for KeyState

fn clone(&self) -> KeyState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyState

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

Formats the value using the given formatter.

impl Default for KeyState

fn default() -> KeyState

Returns the “default value” for a type.
