Struct Evidence 

pub struct Evidence {
    pub cells: usize,
    pub nulls: usize,
    pub booleans: usize,
    pub integers: usize,
    pub floats: usize,
    pub dates: usize,
    pub timestamps: usize,
}

How many of a column’s cells parsed as each type. A cell counts for every type it parses as: 7 is an integer and a float, a date is also a timestamp.

Fields

cells: usize

Every cell.

nulls: usize

Null tokens.

booleans: usize

Booleans.

integers: usize

Integers.

floats: usize

Numbers (integers included).

dates: usize

Dates.

timestamps: usize

Timestamps (dates included).

Implementations

impl Evidence

pub fn values(&self) -> usize

The non-null cells.

pub fn parsed(&self, data_type: InferredType) -> usize

How many non-null cells parse as data_type.

pub fn best(&self) -> InferredType

The narrowest type every non-null cell parses as.

pub fn closest(&self) -> Option<(InferredType, usize)>

The typed reading most cells support, for a text column: (type, count), or None when no cell parses as anything.
