Struct DictValue

pub struct DictValue { /* private fields */ }

This struct stores the scalar value (or array) of one of the following type: double, cv::String or int64. @todo Maybe int64 is useless because double type exactly stores at least 2^52 integers.

Implementations

impl DictValue

pub fn copy(r: &impl DictValueTraitConst) -> Result<DictValue>

pub fn from_bool(i: bool) -> Result<DictValue>

pub fn from_i64(i: i64) -> Result<DictValue>

C++ default parameters

• i: 0

pub fn from_i64_def() -> Result<DictValue>

Note

This alternative version of [from_i64] function uses the following default values for its arguments:

• i: 0

pub fn from_i32(i: i32) -> Result<DictValue>

pub fn from_u32(p: u32) -> Result<DictValue>

pub fn from_f64(p: f64) -> Result<DictValue>

pub fn from_str(s: &str) -> Result<DictValue>
