Branching with if, elseif, and else

#[derive(Oxiplate)]
#[oxiplate = "template.html.oxip"]
struct YourStruct {
    count: i64,
}

print!("{}", YourStruct {
    count: 19,
});

<p>
    {%- if count < 0 -%}
        {{ count }} is negative
    {%- elseif count > 0 -%}
        {{ count }} is positive
    {%- else -%}
        {{ count }} is zero
    {%- endif -%}
</p>

<p>19 is positive</p>

if let and elseif let

Similarly to Rust, let can be used in if and elseif statements.

#[derive(Oxiplate)]
#[oxiplate_inline(html: r#"
<p>
    {%- if let Some(count) = count -%}
        The count is {{ count }}.
    {%- else -%}
        No count provided.
    {%- endif -%}
</p>
"#)]
struct YourStruct {
    count: Option<i64>,
}

assert_eq!("<p>The count is 19.</p>", format!("{}", YourStruct {
    count: Some(19),
}));

Additionally, for single-variable situations where borrowing is acceptable, the = variable part can be skipped (= &variable will be inserted automatically):

#[derive(Oxiplate)]
#[oxiplate_inline(html: r#"
<p>
    {%- if let Some(count) -%}
        The count is {{ count }}.
    {%- else -%}
        No count provided.
    {%- endif -%}
</p>
"#)]
struct YourStruct {
    count: Option<i64>,
}

assert_eq!("<p>The count is 19.</p>", format!("{}", YourStruct {
    count: Some(19),
}));
