|
|
<p>A value can be represented by the target type when it lies within
|
|
the range of scalars supported by the target type.
|
|
For example, a negative integer cannot be represented by an unsigned
|
|
integer type, and an <code>i64</code> with a very high magnitude might not be
|
|
convertible to an <code>i32</code>.
|
|
On the other hand, conversions with possible precision loss or truncation
|
|
are admitted, like an <code>f32</code> with a decimal part to an integer type, or
|
|
even a large <code>f64</code> saturating to <code>f32</code> infinity.</p>

<p>The default implementation tries to convert through <code>from_i64()</code>, and
|
|
failing that through <code>from_u64()</code>. Types implementing this trait should
|
|
override this method if they can represent a greater range.</p>
