Struct serde_json::value::Number [] [src]

pub struct Number { /* fields omitted */ }

Represents a JSON number, whether integer or floating point.

Methods

impl Number
[src]

[src]

Returns true if the number can be represented as i64.

[src]

Returns true if the number can be represented as u64.

[src]

Returns true if the number can be represented as f64.

[src]

Returns the number represented as i64 if possible, or else None.

[src]

Returns the number represented as u64 if possible, or else None.

[src]

Returns the number represented as f64 if possible, or else None.

[src]

Converts a finite f64 to a Number. Infinite or NaN values are not JSON numbers.
