From b9a754c6f91c3d7d2a5aee7a2e979bf4f79e2179 Mon Sep 17 00:00:00 2001 From: Abhishek Shinde Date: Mon, 18 May 2026 20:01:03 +0530 Subject: [PATCH 1/7] doc: upgrade rand dependency to v0.10.1 in book listings and text Upgrades the 'rand' crate dependency from v0.8.5 to v0.10.1 across all chapter listings and updates the corresponding book narrative to reflect the new API structure. Key Changes: - Manifests: Updated 14 Cargo.toml files in listings to point to rand 0.10.1. - Source Code: Migrated 11 main.rs and lib.rs source files under listings/ to: - Bring the new extension trait 'rand::RngExt' into scope instead of 'rand::Rng'. - Replace 'rand::thread_rng().gen_range(1..=100)' with 'rand::rng().random_range(1..=100)'. - Chapter 1: Updated the offline caching command in ch01-01-installation.md to refer to rand@0.10.1. - Chapter 2: Updated ch02-00-guessing-game-tutorial.md to explain RngExt, rand::rng, and random_range. Adjusted all SemVer examples, compiler outputs, and hypotheticals to use 0.10.1 / 0.10.2 / 0.11.0. - Chapter 7: Updated the module path and import system explanation in ch07-04-bringing-paths-into-scope-with-the-use-keyword.md to target the new traits/functions. - Chapter 14: Updated simulated cargo output in ch14-03-cargo-workspaces.md showing rand v0.10.1 being compiled. --- .../listing-02-02/Cargo.toml | 2 +- .../listing-02-03/Cargo.toml | 2 +- .../listing-02-03/src/main.rs | 4 +- .../listing-02-04/Cargo.toml | 2 +- .../listing-02-04/src/main.rs | 4 +- .../listing-02-05/Cargo.toml | 2 +- .../listing-02-05/src/main.rs | 4 +- .../listing-02-06/Cargo.toml | 2 +- .../listing-02-06/src/main.rs | 4 +- .../Cargo.toml | 2 +- .../src/main.rs | 4 +- .../no-listing-04-looping/Cargo.toml | 2 +- .../no-listing-04-looping/src/main.rs | 4 +- .../no-listing-05-quitting/Cargo.toml | 2 +- .../no-listing-05-quitting/src/main.rs | 4 +- .../listing-07-18/Cargo.toml | 2 +- .../listing-07-18/src/main.rs | 4 +- .../no-listing-01-use-std-unnested/Cargo.toml | 2 +- .../src/main.rs | 4 +- .../listing-09-13/Cargo.toml | 2 +- .../listing-09-13/src/main.rs | 4 +- .../Cargo.toml | 2 +- .../src/main.rs | 4 +- .../add/add_one/Cargo.toml | 2 +- .../add/add_one/Cargo.toml | 2 +- src/ch01-01-installation.md | 2 +- src/ch02-00-guessing-game-tutorial.md | 42 +++++++++---------- ...g-paths-into-scope-with-the-use-keyword.md | 4 +- src/ch14-03-cargo-workspaces.md | 4 +- 29 files changed, 62 insertions(+), 62 deletions(-) diff --git a/listings/ch02-guessing-game-tutorial/listing-02-02/Cargo.toml b/listings/ch02-guessing-game-tutorial/listing-02-02/Cargo.toml index eba27a883c..22f02e1859 100644 --- a/listings/ch02-guessing-game-tutorial/listing-02-02/Cargo.toml +++ b/listings/ch02-guessing-game-tutorial/listing-02-02/Cargo.toml @@ -6,4 +6,4 @@ edition = "2024" # See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html [dependencies] -rand = "0.8.5" +rand = "0.10.1" diff --git a/listings/ch02-guessing-game-tutorial/listing-02-03/Cargo.toml b/listings/ch02-guessing-game-tutorial/listing-02-03/Cargo.toml index eba27a883c..22f02e1859 100644 --- a/listings/ch02-guessing-game-tutorial/listing-02-03/Cargo.toml +++ b/listings/ch02-guessing-game-tutorial/listing-02-03/Cargo.toml @@ -6,4 +6,4 @@ edition = "2024" # See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html [dependencies] -rand = "0.8.5" +rand = "0.10.1" diff --git a/listings/ch02-guessing-game-tutorial/listing-02-03/src/main.rs b/listings/ch02-guessing-game-tutorial/listing-02-03/src/main.rs index 0ae11e3d41..c63125c87f 100644 --- a/listings/ch02-guessing-game-tutorial/listing-02-03/src/main.rs +++ b/listings/ch02-guessing-game-tutorial/listing-02-03/src/main.rs @@ -2,14 +2,14 @@ use std::io;
