Struct RenderInput 

pub struct RenderInput<'a> {
    pub date: &'a str,
    pub title: &'a str,
    pub why: &'a str,
    pub rejected: Option<&'a str>,
    pub risk: Option<&'a str>,
    pub tags: &'a [String],
}

Inputs needed to render an entry block.

Kept as a borrow-everything struct so the call site reads cleanly and new optional fields can be added in future versions without breaking callers (they’d compile-error on the missing field and add None).

Example

use logbook::{render_entry_block, RenderInput};

let tags = vec!["refactor".to_string()];
let block = render_entry_block(&RenderInput {
    date: "2026-05-16",
    title: "switched ORM",
    why: "perf",
    rejected: None,
    risk: None,
    tags: &tags,
});
assert!(block.starts_with("## 2026-05-16 — switched ORM\n"));

Fields

date: &'a str

Date string, conventionally YYYY-MM-DD. Not validated by the renderer — pass crate::today if you want today’s date.

title: &'a str

Short single-line title.

why: &'a str

The mandatory why field — the reason for the decision.

rejected: Option<&'a str>

Optional rejected field — alternatives considered and why not. Empty or whitespace-only strings are omitted from the output.

risk: Option<&'a str>

Optional risk field — what could go wrong. Empty or whitespace-only strings are omitted from the output.

tags: &'a [String]

Tags to attach. Per-tag whitespace is trimmed and empty entries are dropped before rendering. An empty slice omits the tags line.

Trait Implementations

impl<'a> Clone for RenderInput<'a>

fn clone(&self) -> RenderInput<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for RenderInput<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
